Infineon Technologies CY90F352TESPMC-GS-A-SPE1

Overview

CY90F352TESPMC-GS-A-SPE1 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 15-channel 8/10-bit ADC. It operates at up to 24 MHz (42 ns instruction cycle), supports LIN-UART ×2, I²C ×1, and delivers automotive-grade operation from −40°C to +125°C - deployed in engine control units and body electronics.

For engineers reviewing the CY90F352TESPMC-GS-A-SPE1 datasheet, CY90F352TESPMC-GS-A-SPE1 pinout, CY90F352TESPMC-GS-A-SPE1 application, or CY90F352TESPMC-GS-A-SPE1 equivalent, key selection criteria include CAN message buffer count (16), Flash security support, sub-clock absence (S-suffix), external bus disable in internal vector mode, and 4-channel output compare timing precision.

Technical Context

The device implements a PLL-based clock system enabling 4–24 MHz machine clock from a 4 MHz crystal, with independent main/sub clock supervision (though sub-clock pins X0A/X1A are omitted per S-suffix). Its CAN controller supports automatic retransmission, remote frame response, and flexible acceptance filtering using full-bit compare or dual partial masks.

Peripheral integration includes two 16-bit free-run timers (FRT0/FRT1), six input capture channels tied to ICU inputs, four output compare channels supporting interrupt-on-match and pulse generation, and a 15-channel ADC with 3 µs conversion time at 24 MHz - all accessible via a 24-bit internal address space and enhanced C-language-compatible instruction set.

FAQ

Is CY90F352TESPMC-GS-A-SPE1 pin-compatible with MB90F352E(S) variants?

Yes - it shares identical LQFP-64 pinout, electrical characteristics, and memory map with MB90F352E(S) and MB90F352TE(S). The "S" suffix confirms absence of sub-clock pins (X0A/X1A), and "T" indicates low-voltage/CPU runaway reset functionality. No hardware redesign is needed when migrating from legacy Cypress part numbers.

Does this MCU support CAN FD or only classical CAN?

This device implements FULL-CAN v2.0 Part A and Part B only, supporting bit rates up to 1 Mbps with standard 11-bit or extended 29-bit identifiers. It does not support CAN FD features such as flexible data-rate switching, larger payloads, or CRC enhancements - those require newer Infineon AURIX or Traveo II families.

What is the purpose of the "GS-A" marking in the part number?

"GS-A" denotes Infineon's Green Standard grade with lead-free (Pb-free), halogen-free, and RoHS-compliant construction, plus A-grade screening for automotive applications. It reflects qualification to AEC-Q100 Grade 1 (−40°C to +125°C) and includes enhanced traceability and lot-control documentation required by Tier 1 suppliers.

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

Yes - the dual-bank architecture allows one bank (e.g., lower 64 KB) to host a certified bootloader while the other (upper 64 KB) runs application firmware. Erase/write operations in one bank occur independently, enabling field updates without interrupting real-time CAN or ADC tasks - a requirement for ISO 26262 ASIL-B software update paths.
