Product details
Overview
CY90F548GSPFR-GE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN 2.0A/B), 128 KB Flash ROM, 4 KB RAM, and QFP-100 package - designed for automotive body control modules requiring deterministic real-time communication, fault-tolerant CAN messaging, and mixed-signal peripheral integration.
For engineers reviewing the CY90F548GSPFR-GE1 datasheet, CY90F548GSPFR-GE1 pinout, CY90F548GSPFR-GE1 application, or CY90F548GSPFR-GE1 equivalent, this page delivers verified technical context, validated pin functions, confirmed CAN timing behavior, exact memory mapping, and real-world automotive use cases - not generic MCU descriptions.
Technical Context
The CY90F548GSPFR-GE1 implements the F2MC-16LX CPU core with 32-bit accumulator, 23 addressing modes, and enhanced C-language support including system stack pointer and barrel shift instructions. It executes instructions in as little as 62.5 ns at 16 MHz machine clock (4 MHz crystal ×4 PLL).
Its dual CAN controllers support flexible mailbox/FIFO hybrid buffering, automatic retransmission, remote frame response, and bit rates up to 1 Mbps. Peripheral subsystems include 8/10-bit 8-channel ADC (26.3 µs conversion), four 8/16-bit PPG timers, dual UARTs with synchronous/asynchronous modes, and 81 general-purpose I/O pins with schmitt-trigger inputs and push-pull outputs.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB90F548GL(S) | Same F2MC-16LX core, 128 KB Flash, but operates at 3.5–5.5 V (wider supply range) and uses single-clock system | Lacks dual UART flexibility; optimized for cost-sensitive entry-level automotive modules with reduced diagnostics | Select when operating voltage may dip below 4.5 V or when external crystal buffer circuitry must be minimized |
| MB90548G(S) | Mask ROM variant (128 KB), identical pinout and peripheral set, but no field-programmable Flash | Suitable for high-volume production where firmware is fixed and security against reverse engineering is critical | Select for mass-produced ECUs with immutable firmware and strict anti-tampering requirements |

FAQ
Does CY90F548GSPFR-GE1 support AEC-Q100 qualification?
Yes - CY90F548GSPFR-GE1 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C) per manufacturer documentation. It undergoes stress testing for HTOL, TCT, ESD, and latch-up per automotive reliability standards, with full test reports available under NDA from Infineon.
What is the maximum CAN bit rate supported in practice?
The device supports up to 1 Mbps CAN bit rate per channel, verified with 16 MHz system clock and standard 60 Ω termination. Real-world operation at 1 Mbps requires ≤40 m cable length with proper stub management; for longer buses, 500 kbps is recommended for robustness.
Can the Flash memory be programmed in-system?
Yes - CY90F548GSPFR-GE1 supports full in-system programming (ISP) via UART0 using embedded Flash algorithm commands (Write, Erase, Suspend, Resume). No external HV programmer is needed; firmware updates can be triggered by host MCU or bootloader over CAN or UART.
Is there hardware support for CAN FD?
No - CY90F548GSPFR-GE1 implements classical CAN 2.0A/B only (ISO 11898-1), with fixed 11-/29-bit identifiers and 0–8 byte payloads. It does not support CAN FD features such as bit rate switching or extended payload lengths beyond 8 bytes.
