Product details
Overview
CY90F352SPFM-GS-DE1 from Cypress Semiconductor (acquired Fujitsu Semiconductor in 2018) is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN 2.0A/B interface, 128 KB on-chip Flash ROM, 4 KB RAM, and 15-channel 8/10-bit ADC - designed for automotive body control modules and industrial CAN node applications requiring deterministic real-time communication and mixed-signal processing.
For engineers reviewing the CY90F352SPFM-GS-DE1 datasheet, CY90F352SPFM-GS-DE1 pinout, CY90F352SPFM-GS-DE1 application, or CY90F352SPFM-GS-DE1 equivalent, key selection criteria include its 42 ns instruction execution time at 24 MHz PLL clock, dual-bank Flash security protection, flexible CAN message buffering (16 mailboxes + FIFO), and LQFP-64 package with automotive-grade −40 °C to +125 °C operation.
Technical Context
This MCU implements the F2MC-16LX CPU core with 24-bit internal addressing, 16 MB memory space, and enhanced C-language support via system stack pointer, barrel shift, and 32-bit accumulator. Its clock system integrates a programmable PLL (×1 to ×6), independent main/sub-clock monitoring, and internal 100 kHz CR oscillator for watch mode.
The peripheral set includes two 16-bit freerun timers (FRT0/FRT1), six 16-bit input capture channels (ICU), four 16-bit output compare channels (OCU), two UARTs with LIN master/slave capability, one I²C interface (400 kbps), and a 15-channel ADC with 3 µs conversion time at 24 MHz - all accessible via bit-configurable I/O ports (51 total).

Use Value: Internal 100 kHz CR oscillator sustains watch mode during main clock failure; Flash security prevents unauthorized firmware access in unattended deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon XC2267M-104F80L | TriCore™ 32-bit core, 80 MHz max, 512 KB Flash, 3× CAN FD channels, no integrated LIN | Higher performance for complex motor control; lacks native LIN support requiring external IC | Select when CAN FD bandwidth >1 Mbps is required and LIN is handled externally or omitted |
| Renesas RL78/F13 | 16-bit RL78 core, 32 MHz max, 128 KB Flash, 1× CAN 2.0B, 21-channel 10-bit ADC, built-in LIN | Lower power (120 µA/MHz), smaller footprint (LQFP-48), but limited CAN buffer depth (8 mailboxes) | Select for cost-sensitive, low-power nodes where LIN integration and compact size outweigh CAN buffer flexibility |
Compared with XC2267M-104F80L and RL78/F13, CY90F352SPFM-GS-DE1 uniquely balances 16-bit efficiency, 16-message CAN buffering, LIN-ready UARTs, and dual-bank Flash security - making it optimal for mid-tier automotive body controllers needing field-upgradable firmware and mixed analog/digital I/O without architectural overdesign.

FAQ
Does CY90F352SPFM-GS-DE1 support CAN FD?
No. This device implements FULL-CAN compliant with ISO 11898-1:2003 (CAN 2.0A/B only), supporting up to 1 Mbps classical CAN frames. It does not support CAN FD's variable bit rate, extended data length, or CRC enhancements. For CAN FD, consider Infineon's AURIX or NXP's S32K series.
What is the purpose of the "S" suffix in CY90F352SPFM-GS-DE1?
The "S" suffix indicates the device omits external sub-clock pins (X0A/X1A) and instead uses the internal 100 kHz CR oscillator for watch mode and low-power timing. This simplifies board layout by eliminating the need for a secondary crystal, while retaining full CAN, ADC, and timer functionality.
Can the 128 KB Flash be partitioned for secure boot and application code?
Yes. The dual-operation Flash architecture supports independent erase/write/read operations across upper and lower banks. Combined with Flash security lock bits (enabled via dedicated command sequence), this allows implementation of secure boot loaders that verify application integrity before execution.
Is external bus interface supported on CY90F352SPFM-GS-DE1?
No. External bus interface capability is excluded in the "S"-suffix variant. Only the non-S versions (e.g., MB90F352A) support 4 MB external memory expansion. CY90F352SPFM-GS-DE1 relies solely on on-chip 128 KB Flash and 4 KB RAM, optimized for self-contained CAN node designs.
