Infineon Technologies CY90F352ESPMC1-GE1

Overview

CY90F352ESPMC1-GE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN 2.0A/B interface, 128 KB dual-operation Flash memory, and 4 KB RAM. It operates at up to 24 MHz (42 ns instruction cycle), supports 15-channel 8/10-bit ADC (3 µs conversion time), and features two 16-bit free-run timers, six input capture channels, and four output compare channels. Designed for automotive body control modules and industrial CAN nodes requiring real-time deterministic communication.

For engineers reviewing the CY90F352ESPMC1-GE1 datasheet, CY90F352ESPMC1-GE1 pinout, CY90F352ESPMC1-GE1 application, or CY90F352ESPMC1-GE1 equivalent, key selection criteria include its CAN message buffer architecture (16 prioritized buffers), sub-clock support (X0A/X1A pins), Flash security feature, and operation over −40°C to +125°C with 3.5–5.5 V supply.

Technical Context

The CY90F352ESPMC1-GE1 implements the F2MC-16LX CPU core with 24-bit internal addressing, supporting bit/byte/word/long-word data types and 23 addressing modes. Its PLL clock multiplier accepts 4 MHz external crystal and generates machine clocks from 4 MHz to 24 MHz in ×1, ×2, ×3, ×4, or ×6 steps - enabling 42 ns minimum instruction execution time.

It integrates a dedicated FULL-CAN controller compliant with ISO 11898-1:2003, supporting automatic retransmission, remote frame response, and flexible acceptance filtering (full-bit compare/mask or two partial masks). The CAN interface includes wake-up capability and operates up to 1 Mbps, with message buffers independently configurable for TX/RX roles and priority-based arbitration.

FAQ

Is CY90F352ESPMC1-GE1 pin-compatible with MB90F352ES?

Yes - CY90F352ESPMC1-GE1 is a direct replacement for MB90F352ES with identical LQFP-64 pinout, electrical characteristics, and memory map. Infineon maintains full backward compatibility, including identical reset behavior, clock configuration registers, and peripheral address mapping per Document 002-04493 Rev. *A.

Does this MCU support CAN FD?

No - CY90F352ESPMC1-GE1 implements only classical CAN 2.0A/B (ISO 11898-1:2003) with fixed 11-bit identifiers and 8-byte payloads. It does not support CAN FD's variable data length, bit-rate switching, or CRC enhancements. For CAN FD, consider Infineon's AURIX™ TC3xx series.

What debug interface does CY90F352ESPMC1-GE1 use?

It uses Cypress's proprietary JTAG-based ICE interface compatible with the MB2147-01 emulator. Debug access requires TOOL VCC jumper configuration and supports full-speed execution, breakpoint setting, and Flash programming via the on-chip bootloader - no SWD or ARM-style debug port is present.

Can the 128 KB Flash be partitioned for secure boot and application code?

Yes - the dual-operation Flash supports independent erasure and write protection per 8 KB block. Boot code can reside in protected lower bank while application runs from upper bank; Flash Security Feature prevents unauthorized read-out of either region, satisfying basic OEM bootloader integrity requirements.
