Microchip Technology

High-performance secure memory providing 128Kbit of user memory with advanced security and cryptographic features built-in. The user memory is divided into sixteen 1-KByte zones, each of which may be individually assigned different security access rights or which can be effectively combined together to provide space for one to sixteen data files.

Microchip CryptoRF?? integrates a 13.56MHz RF interface into Microchip CryptoMemory?? to create a contactless secure RFID solution with advanced security and cryptographic features. The device is optimized as contactless secure memory for RF tags and secure data storage without requiring an internal microprocessor. This device contains 16Kb of user memory and 2Kb of configuration memory containing: eight sets of read/write passwords, four crypto key sets, security access registers for each user zone, and password/key registers for each zone. The maximum communication range between the reader antenna and contactless card is approximately 10cm when used with an RFID reader that transmits the maximum ISO/IEC 14443-2 RF power level. The RF interface powers the other circuits.

High-performance secure memory providing 256Kbit of user memory with advanced security and cryptographic features built-in. The user memory is divided into sixteen 2-KByte zones, each of which may be individually assigned different security access rights or which can be effectively combined together to provide space for one to sixteen data files.

The AT88SC3216C member of the CryptoMemory® family is a high-performance secure memory providing 32 Kbits of user memory with advanced security and cryptographic features built in. The user memory is divided into 16 256-byte zones, each of which may be individually set with different security access rights or effectively combined together to provide space for 1 to 16 data files.

The Microchip ATA663231 system basis chip is a fully integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2, with a low-drop voltage regulator with 3.3V/85mA. The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful slave nodes in LIN bus systems. Microchip ATA663231 is designed to handle the low-speed data communication in vehicles (for example, in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20Kbaud. The bus output is designed to withstand high voltage. Sleep mode and silent mode guarantee minimized current consumption even in the case of a floating or a shorted LIN bus. The voltage regulator is a fully integrated low-drop regulator working down to a supply voltage of 2.3V with best-in-class current consumption in linear mode (2V<VVS<5V) with less than 170µA. This enables storing data within the MCU during system shutdown even in case of an unexpected power supply interruption. The device is available in DFN8 package with wettable flanks and pin assignment according to OEM hardware requirements for LIN-, CAN-, and Flexray- interfaces, rev. 1.3.
