Infineon Technologies CY90F352PFM-G-SPE1

Overview

CY90F352PFM-G-SPE1 from Fujitsu Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN 2.0A/B interface, 128 KB Flash ROM, 4 KB RAM, and operation up to 24 MHz (at +125°C). It features a 42 ns instruction execution time (with 4 MHz crystal ×6 PLL), 15-channel 8/10-bit ADC (3 µs conversion), and dual-bank Flash for concurrent read/erase-designed for automotive body control modules requiring CAN-based sensor/actuator communication.

For engineers reviewing the CY90F352PFM-G-SPE1 datasheet, CY90F352PFM-G-SPE1 pinout, CY90F352PFM-G-SPE1 application, or CY90F352PFM-G-SPE1 equivalent, key selection criteria include its 1-channel CAN compliance (up to 1 Mbps), sub-clock support (100 kHz internal CR oscillator), LQFP-64 package with 51 I/O ports, and flash security protection-critical for ECU firmware integrity in harsh-temperature environments.

Technical Context

This MCU implements the F2MC-16LX CPU core with 24-bit internal addressing and a 16 MB memory space, supporting C-language compilation via enhanced multiply-divide instructions and a 32-bit accumulator. Its clock system integrates a programmable PLL (×1–×6), independent main/sub clock monitoring, and four low-power modes (Sleep, Main Timer, PLL Timer, Watch).

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 capability, one I²C interface (400 kbps), and an external bus interface supporting up to 4 MB address space-enabling flexible expansion in distributed automotive subsystems.

FAQ

Does CY90F352PFM-G-SPE1 support CAN FD?

No. CY90F352PFM-G-SPE1 implements FULL-CAN compliant with ISO 11898-1:2003 (CAN 2.0A/B), supporting up to 1 Mbps classical CAN frames only. It does not support CAN FD's variable bit rate, extended data length, or CRC enhancements. For CAN FD, consider Socionext's newer MB96F series or Renesas RH850.

What is the purpose of the "S" suffix in MB90F352S variants?

The "S" suffix denotes absence of external sub-clock pins (X0A/X1A); those variants use only the internal 100 kHz CR oscillator for sub-clock operation. CY90F352PFM-G-SPE1 is an "S" variant, eliminating need for external 100 kHz crystal while retaining full clock monitor functionality on main oscillator.

Can the 15-channel ADC operate simultaneously at 10-bit resolution?

No. The 15-channel ADC is a single SAR converter with multiplexed inputs. While all 15 channels are accessible, conversion is sequential-not parallel. At 24 MHz machine clock, minimum conversion time is 3 µs per channel including sampling, enabling up to ~333 kSPS aggregate throughput.

Is external bus interface supported in CY90F352PFM-G-SPE1?

Yes. CY90F352PFM-G-SPE1 includes a full external bus interface supporting up to 4 MB address space, 8/16-bit data bus width, and programmable wait states-enabling connection to external SRAM, NOR Flash, or peripherals like LCD controllers in complex automotive HMI designs.
