Overview
CY90352ESPMC-GS-242E1 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 requiring robust CAN communication and real-time I/O handling.
For engineers reviewing the CY90352ESPMC-GS-242E1 datasheet, CY90352ESPMC-GS-242E1 pinout, CY90352ESPMC-GS-242E1 application, or CY90352ESPMC-GS-242E1 equivalent, key selection criteria include CAN message buffer configuration (16 buffers), dual-bank Flash security, sub-clock support (X0A/X1A pins), and industrial-grade temperature range (−40°C to +125°C).
Technical Context
The CY90352ESPMC-GS-242E1 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 input and generates machine clocks from 4 MHz to 24 MHz, 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 on error, Remote Frame response, and flexible acceptance filtering (full-bit compare/mask, two partial masks). The 16 prioritized message buffers support concurrent transmission/reception at up to 1 Mbps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB90F352E(S) | Same F2MC-16LX core, identical pinout and peripheral set, but uses original Cypress ordering prefix and lacks Infineon branding | No functional difference; used interchangeably in legacy designs prior to Infineon acquisition | Select when sourcing from pre-acquisition inventory or for backward compatibility with existing PCB layouts |
| R5F100LEAFB#30 | Renesas RL78/G13 core (16-bit), 128 KB Flash, but no native CAN - requires external CAN controller or software CAN stack | Lacks integrated FULL-CAN; suitable only where CAN traffic volume is low or external PHY + software stack is acceptable | Choose only if migrating from RL78 ecosystem and CAN bandwidth requirements are ≤50 kbps |

FAQ
What is the maximum CAN bit rate supported by CY90352ESPMC-GS-242E1?
The device supports CAN bit rates up to 1 Mbps, verified per ISO 11898-1:2003 compliance. This capability is enabled by its FULL-CAN controller's hardware message buffering and arbitration logic, allowing full utilization of high-speed automotive networks without CPU overhead.
Does CY90352ESPMC-GS-242E1 support in-system programming (ISP) via CAN?
Yes - the device supports ISP through its built-in bootloader, which accepts CAN frames containing Flash programming commands (Erase, Write, Verify). Programming requires no external debugger; only a CAN interface and valid security key (if Flash security is enabled).
Is the sub-clock oscillator (X0A/X1A) functional in CY90352ESPMC-GS-242E1?
Yes - this part number includes the "S" suffix indicating sub-clock support. X0A and X1A accept an external 100 kHz crystal, enabling independent watch timer operation and ultra-low-power wake-up modes without relying on the main oscillator.
How many simultaneous ADC conversions can be triggered externally?
The 15-channel ADC supports single-shot or continuous conversion triggered by any of eight external sources (e.g., timer overflow, CAN message arrival, GPIO edge). Only one conversion starts per trigger event, but up to 15 channels may be sequenced in a single scan with 3 µs per channel at 24 MHz.
