Infineon Technologies CY90F352TESPMC-GE1

Overview

CY90F352TESPMC-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 - deployed in automotive body control modules requiring real-time CAN messaging and sensor interfacing.

For engineers reviewing the CY90F352TESPMC-GE1 datasheet, CY90F352TESPMC-GE1 pinout, CY90F352TESPMC-GE1 application, or CY90F352TESPMC-GE1 equivalent, key selection criteria include CAN message buffer configuration (16 buffers), Flash security enablement, sub-clock absence (S-suffix device), and -40°C to +125°C operation with 3.5–5.5 V supply range.

Technical Context

The CY90F352TESPMC-GE1 implements the F2MC-16LX CPU core with 24-bit addressing, supporting bit/byte/word/long-word data types and 23 addressing modes optimized for embedded control. Its PLL multiplies a 4 MHz external clock by 1–6× to generate up to 24 MHz machine clock, enabling deterministic 42 ns instruction execution.

It integrates a FULL-CAN controller compliant with ISO 11898-1:2003 (CAN 2.0A/B), featuring automatic retransmission, Remote Frame response, and flexible acceptance filtering (full-bit compare/mask, dual partial masks). The CAN wake-up function enables low-power sleep mode activation via bus activity.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now owns and supports the entire F2MC-16LX microcontroller portfolio, including automotive-qualified 16-bit MCUs with CAN and LIN interfaces.

The MB90350E series - including CY90F352TESPMC-GE1 - was originally developed by Cypress for automotive and industrial real-time control applications demanding robust CAN communication, flash security, and extended temperature operation.

FAQ

Does CY90F352TESPMC-GE1 support CAN FD?

No. The integrated CAN controller conforms strictly to ISO 11898-1:2003 (CAN 2.0A/B) and does not implement CAN FD protocol features such as variable bit rate, extended data length, or CRC enhancements. It supports up to 1 Mbps classical CAN with 16 message buffers and full acceptance filtering.

Is external bus interface available on this part?

No. CY90F352TESPMC-GE1 is configured in internal vector mode and disables the external bus interface. This is confirmed in the datasheet: "MB90F352E(S) … External bus Interface can not be used in internal vector mode." All memory and peripheral access occurs internally via the 128 KB Flash and 4 KB SRAM.

What is the purpose of the 'S' suffix in CY90F352TESPMC-GE1?

Per Cypress documentation, the 'S' suffix indicates absence of sub-clock crystal pins (X0A/X1A). This device uses only the internal CR oscillator for sub-clock operation and cannot connect an external 32.768 kHz crystal - simplifying layout and reducing BOM cost in applications where sub-clock precision is not required.

Can the 15-channel ADC operate simultaneously?

No. The 15-channel 8/10-bit SAR ADC shares a single conversion engine; channels are scanned sequentially. Conversion time per channel is 3 µs (including sampling) at 24 MHz, allowing full 15-channel scan in ≤45 µs - sufficient for most automotive sensor acquisition cycles below 10 kHz.
