Overview
CY90F352ESPMC1-GSE1 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 real-time CAN communication and deterministic timing.
For engineers reviewing the CY90F352ESPMC1-GSE1 datasheet, CY90F352ESPMC1-GSE1 pinout, CY90F352ESPMC1-GSE1 application, or CY90F352ESPMC1-GSE1 equivalent, key selection criteria include its dual-bank Flash security, CAN wake-up capability, sub-clock-independent watchdog, LIN-UART dual-channel support, and −40°C to +125°C operation with automotive-grade I/O voltage level configuration.
Technical Context
The CY90F352ESPMC1-GSE1 implements the F2MC-16LX CPU core with 24-bit addressing, 32-bit accumulator, and C-language-optimized instruction set including barrel shift and enhanced multiply/divide. Its PLL clock multiplier accepts 4 MHz external crystal and generates 4–24 MHz machine clocks with selectable division/multiplication ratios.
It integrates a dedicated FULL-CAN controller with 16 prioritized message buffers, acceptance filtering (full-bit compare/mask), automatic retransmission, and remote frame response - all compliant with ISO 11898-1:2003. The CAN module supports up to 1 Mbps and includes dedicated wake-up detection on bus activity.

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 |
|---|---|---|---|
| MB90F352ESPMC1-GSE1 | Same die, legacy Cypress ordering prefix; identical electrical specs and pinout | No functional difference; same automotive qualification and documentation | Preferred for new designs requiring Infineon's long-term supply commitment and updated support infrastructure |
| SPC560B50L5 | 32-bit Power Architecture core; higher MIPS, integrated CAN FD, no LIN-UART; larger footprint (LQFP-100) | Targets next-gen powertrain and ADAS; lacks native LIN support - requires external transceiver or software emulation | Select when migrating to CAN FD or requiring >100 MHz processing; not drop-in compatible due to architecture and pin count mismatch |

FAQ
Is CY90F352ESPMC1-GSE1 pin-compatible with MB90F352ESPMC1-GSE1?
Yes - CY90F352ESPMC1-GSE1 and MB90F352ESPMC1-GSE1 share identical LQFP-64 pinout, electrical characteristics, and functional behavior. The "CY" prefix reflects Infineon's post-acquisition branding; no hardware or firmware changes were introduced. Both part numbers map to the same silicon die and datasheet (002-04493 Rev. *A).
Does this MCU support CAN FD?
No - CY90F352ESPMC1-GSE1 implements only classical CAN 2.0A/B (ISO 11898-1:2003) with up to 1 Mbps data rate. It lacks CAN FD features such as flexible data-length payloads, bit-rate switching, and CRC21 checksum. For CAN FD, consider Infineon's AURIX™ TC3xx family or SPC560B50L5.
What is the purpose of the dual-operation Flash memory?
Dual-operation Flash allows concurrent read from one bank while erasing or programming the other - enabling seamless firmware updates without interrupting real-time CAN message handling or timer-based control loops. This eliminates system freezes during field upgrades and supports robust OTA deployment in automotive ECUs.
Can the LIN-UART operate in both master and slave modes?
Yes - each of the two LIN-UART channels supports full master/slave functionality per LIN 2.2 specification. The hardware includes dedicated baud rate generators, break detection, sync field handling, and identifier-based checksum calculation - enabling the device to serve as LIN master coordinating multiple slaves or as a configurable slave node in distributed architectures.
