Panasonic introduces new Amorton indoor solar cell series

Wed, May 01, 2024

Panasonic’s hydrogenated amorphous silicon (a-Si:H) solar cells, known as Amorton, power indoor and outdoor applications like IoT devices, watches, sensor nodes, asset trackers, or remote controls. Amorton can harvest energy reliably and sustainably even in low light and artificial light environments.

Now Panasonic introduces its latest Amorton solar cell series: Named AMG-1401C and AMG-1701C, the new products benefit from a nearly perfect black-reflective surface and much higher efficiency (+20%). These breakthroughs have been made possible thanks to an optimised production process, which significantly increased the active area compared to the previous generation. The result is a 20% increase in efficiency, making the new AMG-series one of the most efficient indoor amorphous solar cells on the market today. The AMG-1401C and AMG-1701C, which are based on glass substrates, are 1.1mm thin, generate approx. 8uW/cm2 at 200lux per active area.

The external dimensions are only slightly larger than the active area, which means the space and material consumption in the final application can be optimized. The AMG-1401C with external dimensions of 41.4mm x 26.1mm generates a maximum of 77.8uW at 200 lux. The cell voltage is 2.2V, which means it can be combined with many power management ICs available in the market.

Embedded security using Microchip’s PIC32CK 32-bit MCUs with hardware security module

Tue, Apr 30, 2024

New legislation takes effect in 2024, mandating stricter requirements on cybersecurity on everything from consumer IoT devices to critical infrastructure. Meeting these new security compliance requirements from a product and supply chain perspective can be complex, costly and time-consuming. To provide developers with an embedded security solution that allows them to design applications that comply with these requirements, Microchip has announced the new family of PIC32CK 32-bit microcontrollers (MCUs) with an integrated Hardware Security Module (HSM) subsystem and Arm Cortex-M33 core featuring TrustZone technology to help isolate and secure the device.

The PIC32CK SG is the first 32-bit device on the market that combines the strong security of an HSM with TrustZone technology, a hardware-based secure privilege environment. Microchip’s latest innovation for mid-range MCUs provides designers with a cost-effective embedded security solution for their products that meets the latest cybersecurity mandates. The inclusion of an HSM provides a high level of security for authentication, secure debug, secure boot and secure updates, while TrustZone technology provides an additional level of protection for key software functions. The HSM can accelerate a wide range of symmetric and asymmetric cryptography standards, true random number generation and secure key management.

The PIC32CK MCUs from Microchip are designed to support ISO 26262 functional safety and ISO/SAE 21434 cybersecurity standards. For increased flexibility and cost efficiency, the PIC32CK MCU family offers a wide range of options to tune the level of security, memory and connectivity bandwidth based on the end application’s requirements. Options include up to 2 MB dual-panel Flash and 512 KB SRAM, with various connectivity options like 10/100 Ethernet, CAN FD and USB.

For product supply chains that require additional security and safety protection such as in industrial designs, medical devices, home appliances and consumer IoT devices, the PIC32CK will be supported with Microchip’s Trust Platform Design Suite for provisioning as a service. This platform enables the secure factory provisioning of keys, certificates and IP without the need to reveal these secrets within the supply chain.

The 32-bit PIC32CK MCU family is supported by Microchip’s software platforms including MPLAB® Harmony v3 and Trust Platform Design Suite. The PIC32CK family is also supported by the PIC32CK SG and PIC32CK GC Curiosity Ultra Development Boards including the EV33A17A and EV44P93A.

maXTouch touchscreen controller family from Microchip expands with additional security

Mon, Apr 29, 2024

As we see an increased number of electric vehicles (EVs) on the road, the necessary charging infrastructure must expand to meet the increased demand. Adding credit card payment options to EV chargers is becoming a standard practice in many countries—and is a mandate in the European Union—and chargers need to meet Payment Card Industry (PCI) security standards. To help EV charger designers protect their payment architectures, Microchip has launched the MXT2952TD 2.0 family of secure touchscreen controllers.

Typical touch-enabled human machine interface (HMI) and radio frequency identification (RFID) combination-based payment systems are vulnerable to hacking attacks via malicious software updates or man-in-the-middle attacks when a user enters their personal identification number (PIN) on the touchscreen. Physical mesh barriers and sensors are often used around these integrated circuits (ICs) for protection from hacking. Constant reflashing of software and device resets are used to help safeguard software integrity. The MXT2952TD 2.0 family is designed to encrypt touch data and cryptographically authenticate software updates to minimise risk and meet PCI certification compliance standards. When the RFID reader IC and the touchscreen controller are on different printed circuit boards (PCBs), it is especially difficult and expensive to build physical barriers for hack protection. Embedded firmware on the MXT2952TD 2.0 provides a more easily implemented solution for EV charger manufacturers to remain compliant with security regulations and avoid the cost of adding a second, expensive touchscreen payment module to the charger.

The outdoor nature of EV charger HMIs demand they withstand harsh weather conditions, function accurately in the presence of moisture and are resistant to vandalism. MXT2952TD 2.0 touch controller-based touchscreens remain effective when designed with IK10 standard 6 mm-thick glass, anti-reflective, anti-glare and anti-fingerprint coatings and IR filter/UV filter layers. Microchip’s proprietary differential touch sensing delivers exceptional noise immunity for superior touch performance even when used with thick gloves.

“The maXTouch 2952TD 2.0 family provides EV charger designers with a cost-effective, secure design architecture for implementing credit card payments with PIN entry on their touchscreens,” said Patrick Johnson, senior corporate vice present overseeing Microchip’s human machine interface division. “Combined with the rugged, outdoor HMI touchscreen technology that Microchip’s maXTouch portfolio is known for, the new addition to the 2952TD family of touchscreen controllers offers our customers secure designs and the exceptional touch performance necessary for outdoor applications.”

In addition to EV chargers, the MXT2952TD 2.0 family is well-suited for most unattended outdoor payment terminals such as parking meters, bus ticketing meters and other types of point-of-sale (POS) systems. The 2952TD 2.0 is specifically optimised for 20” screen sizes and its sister part, the MXT1664TD, is available for 15.6” screen sizes.

Standard maXTouch family development tools are available including maXTouch Studio Integrated Development Environment (IDE) and maXTouch Analyser, a production end-of-line test/inspection tool.

Microchip also has a number of factory-trained global touch sensor module partners to help support custom touch sensor and/or touchscreen display designs.
