Microchip Technology AVR32SD20/28/32 AVR® SD 8-Bit Microcontrollers
Microchip Technology AVR32SD20/28/32 AVR® SD 8-Bit Microcontrollers (MCUs) incorporate the AVR CPU with a hardware multiplier running at clock speeds up to 20MHz. The MCUs offer 32/64KB of flash, 4/8KB of SRAM, and 256 bytes of EEPROM. The Microchip AVR32SD20/28/32 MCUs are available in 20-, 28-, 32-, and 48-pin packages. The family offers a flexible and low-power architecture, including an event system, accurate analog features, and advanced digital peripherals. The AVR SD provides a dual-core lockstep CPU, single-error-correcting and double-error-detecting (SECDED) ECC on flash, EEPROM/SRAM, an error controller for functional safety, and a program and debug interface disable (PDID) for security. These microcontrollers comply with ISO 26262 (ASIL C) and IEC 61508 (SIL 2) safety standards, ensuring suitability for automotive safety systems, industrial automation, and medical devices. The robust performance and reliability also make these MCUs ideal for consumer electronics and security systems.
