Dual-core architecture and memory ceiling
The CYT2B97CACQ0AZSGST pairs a Cortex-M0+ running at 100 MHz with a Cortex-M4F at 160 MHz — the M0+ handles housekeeping and safety watchdog tasks while the M4F runs the application and signal-processing loops, splitting the real-time load without a separate supervisor MCU. On-chip memory totals 2.0625 MB of flash, 256 KB of RAM, and 128 KB of EEPROM emulation — enough for a dual-image over-the-air update scheme with a fallback bootloader, keeping external serial flash off the BOM.
Analog front-end and connectivity
A 72-channel 12-bit SAR ADC covers multi-sensor acquisition — battery-cell voltage monitoring, thermistor strings, or current-shunt inputs — without an external multiplexer eating board space and adding settling delay. CAN, LIN, SPI, I²C, and UART/USART interfaces cover the common automotive and industrial fieldbus set; the hardware crypto accelerator (AES, SHA, TRNG) enables secure CAN-FD message authentication and secure boot without loading the M4F core.
Package and board-fit
122 GPIOs are available — enough for a parallel TFT display, a keypad matrix, or multiple sensor interfaces without a port expander.
ROHS3 compliant, with no exemption-based restrictions for EU or global shipping.
