Infineon Technologies CY90F549GPF-GE1

Overview

CY90F549GPF-GE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN 2.0A/B interfaces, 256 KB Flash ROM, 6 KB RAM, and 100-pin LQFP package. It operates at up to 16 MHz (via on-chip PLL ×4), delivers 62.5 ns minimum instruction execution time, and targets automotive body control modules requiring CAN-based distributed networking and real-time I/O handling.

For engineers reviewing the CY90F549GPF-GE1 datasheet, CY90F549GPF-GE1 pinout, CY90F549GPF-GE1 application, or CY90F549GPF-GE1 equivalent, key selection criteria include dual-CAN timing compliance, Flash programmability in-system, 8/10-bit A/D conversion with 26.3 µs per channel, and support for external bus expansion up to 16 Mbytes.

Technical Context

The CY90F549GPF-GE1 implements the proprietary F2MC-16LX CPU core with 32-bit accumulator, 23 addressing modes, and enhanced C-language support including system stack pointer and barrel shift instructions.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability microcontrollers and programmable solutions for automotive, industrial, and IoT markets.

The MB90F540G/545G series was developed specifically for cost-sensitive, high-volume automotive ECUs needing dual CAN 2.0B connectivity, Flash-based field-upgradability, and robust operation from −40 °C to +105 °C.

FAQ

Is CY90F549GPF-GE1 pin-compatible with other MB90F54xG(S) variants?

Yes-CY90F549GPF-GE1 uses the same LQFP-100 footprint and pin assignment as MB90F543G(S), MB90F546G(S), and MB90F548G(S). Differences lie in Flash size (256 KB vs. 128 KB), RAM (6 KB vs. 4–8 KB), and clock system (two-clock vs. one-clock variants), but all share identical peripheral pin mapping and electrical characteristics.

Does CY90F549GPF-GE1 support CAN FD?

No-CY90F549GPF-GE1 implements FULL-CAN compliant with ISO 11898-1:2003 (CAN 2.0A/B only), supporting up to 1 Mbps with standard and extended identifiers. It does not support CAN FD features such as flexible data-rate, larger payloads, or CRC enhancements.

What debug interface does CY90F549GPF-GE1 provide?

CY90F549GPF-GE1 supports on-chip debugging via the HST (Host Interface) pin and dedicated emulator pod (MB2145-507). It does not include SWD or JTAG; debugging requires Cypress's proprietary emulation hardware and associated development tools compatible with the F2MC-16LX architecture.

Can the internal PLL generate a 20 MHz system clock?

No-the on-chip PLL supports multiplication factors of ×1, ×2, ×3, ×4, or ÷2 only. With a 4 MHz crystal, maximum output is 16 MHz (×4); a 5 MHz crystal yields 20 MHz, but the datasheet specifies guaranteed operation only with 4 MHz ±0.5% crystals and 4.5–5.5 V supply, limiting practical max system clock to 16 MHz under validated conditions.
