Infineon Technologies CY90F497GPFM-G-FLE1

Overview

CY90F497GPFM-G-FLE1 from Cypress Semiconductor (originally Fujitsu Microelectronics) is a 16-bit F2MC-16LX microcontroller with on-chip full-CAN interface, 64 KB Flash ROM, 2 KB RAM, and 49 general-purpose I/O ports. It operates from 4.5 V to 5.5 V, supports 16-MHz machine clock (62.5 ns min instruction time), and targets real-time control in automotive body electronics and industrial CAN nodes.

For engineers reviewing the CY90F497GPFM-G-FLE1 datasheet, CY90F497GPFM-G-FLE1 pinout, CY90F497GPFM-G-FLE1 application, or CY90F497GPFM-G-FLE1 equivalent, key selection criteria include CAN 2.0A/B compliance, 8/10-bit 8-channel ADC with 6.13 μs conversion time, dual UART (SCI) with up to 2 Mbps sync mode, 16-bit I/O timer with 4-channel input capture, and LQFP64 package with validated 0.65 mm pitch.

Technical Context

This MCU implements the F2MC-16LX architecture with 351 instructions, 24-bit internal addressing, and a 32-bit accumulator for long-word arithmetic. It integrates a PLL clock multiplier enabling 4–16 MHz machine clock from a 4-MHz crystal, and supports external bus mode with selectable 8/16-bit width.

The peripheral set includes one CAN controller (8 message buffers, 10 kbps–1 Mbps bit rate), two UARTs (SCI0/SCI1) with full-duplex double buffering, an 8/10-bit 8-channel ADC, four 8-bit or two 16-bit PPG timers, and a 16-bit I/O timer with free-run and input-capture capability across four channels.

Manufacturer

Cypress Semiconductor acquired Fujitsu Microelectronics' microcontroller business in 2012, inheriting the MB90xxx F2MC-16LX product line and continuing its support for legacy automotive and industrial designs.

This device belongs to the MB90495G Series - a family of 16-bit CAN-capable microcontrollers designed specifically for deterministic real-time control in harsh electrical environments where bus reliability, low-latency interrupt response, and mixed-signal integration are critical.

FAQ

What is the maximum CAN bit rate supported by CY90F497GPFM-G-FLE1?

The CAN controller supports bit rates from 10 kbps to 1 Mbps when operating with a 16-MHz machine clock. Actual achievable rate depends on network topology, termination, and oscillator tolerance; 500 kbps is typical for robust 2-node automotive body networks with 30 m cable length and ±0.5% crystal accuracy.

Does CY90F497GPFM-G-FLE1 support in-system programming (ISP)?

Yes - it features on-chip Flash memory programmable via the on-chip serial programming interface (SPI-compatible) using the RST and MD pins. Programming requires a dedicated Fujitsu/Cypress programmer (e.g., MB2145-507) and supports block erase, byte write, and verification without removing the device from the PCB.

How many independent PWM outputs can be generated simultaneously?

Up to eight independent PWM outputs are possible: two 16-bit PPG timers (each configurable as two 8-bit or one 16-bit channel) provide four 8-bit or two 16-bit PWM signals, and the 16-bit I/O timer's TOT0/TOT1 outputs add two more, totaling six hardware PWMs - with software-timed GPIO toggling extending to eight if needed.

Is the ADC capable of simultaneous sampling across multiple channels?

No - the 8-channel 8/10-bit ADC performs sequential conversions only. However, it supports continuous conversion mode across up to 8 linked channels with automatic channel sequencing and result storage in dedicated registers, achieving effective throughput of ~163 kSPS aggregate when configured for 8-bit resolution and minimal sampling time.
