Product details
Overview
CY90F548GLSPF-GSE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN 2.0A/B interfaces, 128 KB Flash ROM, 4 KB RAM, and 100-pin LQFP package. It operates at up to 16 MHz (via on-chip PLL ×4), supports 8/10-bit ADC (8 channels, 26.3 µs conversion), and targets automotive body control modules requiring CAN-based distributed sensing and actuation.
For engineers reviewing the CY90F548GLSPF-GSE1 datasheet, CY90F548GLSPF-GSE1 pinout, CY90F548GLSPF-GSE1 application, or CY90F548GLSPF-GSE1 equivalent, key selection criteria include dual-CAN timing determinism, Flash reprogrammability in-circuit, 3.5–5.5 V operation for battery-supplied ECUs, and peripheral integration including UART0/1, PPG timers, and EI2OS intelligent I/O service.
Technical Context
The CY90F548GLSPF-GSE1 implements the proprietary F2MC-16LX CPU core with 32-bit accumulator, 23 addressing modes, and enhanced C-language support via system stack pointer and barrel shift instructions. Its dual CAN controllers feature flexible mailbox/FIFO mixing, automatic retransmission, and 1 Mbps data rate compliance with ISO 11898-1.
Peripheral subsystems include four 8/16-bit PPG timer channels, eight input capture and four output compare channels on the 16-bit I/O timer, dual full-duplex UARTs with synchronous/asynchronous modes (up to 2 Mbps), and an 8-channel 8/10-bit ADC with external trigger start and selectable resolution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP#30 | 32-bit RX66T core, 512 KB Flash, single CAN FD, 3.3 V only | Higher performance for motor control algorithms but lacks dual classical CAN and 5 V tolerance | Select when migrating to CAN FD or requiring floating-point math acceleration |
| SPC560B50L5 | Power Architecture e200z0, 512 KB Flash, dual CAN 2.0B, 5 V tolerant, BGA-100 | Same dual-CAN capability but requires external voltage supervisor and lacks integrated PPG timers | Select for ASIL-B functional safety compliance where SPC5 Studio toolchain is mandated |
Compared with R5F566TEADFP#30 and SPC560B50L5, the CY90F548GLSPF-GSE1 uniquely combines 5 V operation, dual classical CAN, Flash reprogrammability, and integrated PPG timers in LQFP-100-making it optimal for cost-sensitive, legacy-CAN automotive modules needing long-term supply stability.

The CY90F548GLSPF-GSE1 belongs to the MB90540G/545G series, engineered specifically for automotive body electronics requiring dual-CAN communication, Flash-based firmware agility, and robust operation across −40 °C to +105 °C.
FAQ
Does CY90F548GLSPF-GSE1 support CAN FD?
No. The device implements FULL-CAN compliant with ISO 11898-1:2003 (CAN 2.0A/B), supporting up to 1 Mbps classical frame format only. It does not include CAN FD arbitration or data phase enhancements, nor does its CAN controller support bit-rate switching or extended data length.
What is the minimum supply voltage for reliable Flash programming?
Flash programming requires VCC ≥ 4.5 V per datasheet specification. At 3.5–4.4 V operation, only RAM and peripheral functions remain active; Flash write/erase operations are disabled to prevent corruption, and the embedded algorithm returns error flag 0x03 (voltage violation).
How many CAN message buffers are allocated per channel?
Each of the two CAN channels supports up to 16 configurable message buffers, configurable as mailboxes or FIFO entries. Buffer assignment is fully software-defined via CAN control registers (CANnMBCR), enabling mixed-mode usage-for example, 8 mailboxes + 1 FIFO of depth 8 per channel.
Is external crystal required for CAN timing accuracy?
Yes. CAN bit timing stability depends on the primary oscillator (X0A/X1A) driving the PLL. A 4 MHz ±0.2% crystal is specified for 1 Mbps operation; using RC oscillation or secondary 32 kHz sub-clock results in cumulative timing error exceeding ISO 11898-1 synchronization tolerance.
