Product details
Overview
CY90F546GPFR-GE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN V2.0A/B), 256 KB Flash ROM, 8 KB RAM, and 81 general-purpose I/O ports. It features an on-chip PLL supporting 16 MHz system clock (62.5 ns min instruction time), 8/10-bit 8-channel ADC (26.3 µs conversion), and integrated peripherals including UART0/UART1, 16-bit timers, PPG, and EI2OS - designed for automotive body control and industrial CAN-based distributed systems.
For engineers reviewing the CY90F546GPFR-GE1 datasheet, CY90F546GPFR-GE1 pinout, CY90F546GPFR-GE1 application, or CY90F546GPFR-GE1 equivalent, key selection criteria include dual-CAN conformance, Flash programmability with block protection, 32-bit accumulator support for C-language math, and QFP-100 package compatibility with automotive-grade −40°C to +105°C operation.
Technical Context
The CY90F546GPFR-GE1 implements the proprietary F2MC-16LX CPU core with 23 addressing modes, enhanced bit manipulation, and signed multiply/divide instructions optimized for real-time embedded control. Its dual CAN controllers support mixed mailbox/FIFO buffering, automatic retransmission, and up to 1 Mbps data rate with full acceptance filtering.
Peripheral integration includes two full-duplex UARTs (asynchronous/synchronous modes), four 8/16-bit PPG channels, eight 16-bit input capture inputs, four 16-bit output compare outputs, and a 16-bit free-run timer with match-clear functionality - all synchronized to the same PLL-derived system clock (fsys = 16 MHz).

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 |
|---|---|---|---|
| MB90F549G(S)-GE1 | Same F2MC-16LX core, identical dual-CAN and peripheral set, but 256 KB Flash + 6 KB RAM (vs. 8 KB) | Lower RAM margin for multi-threaded diagnostics or large CAN message queues | Select when RAM usage is constrained and external memory expansion is acceptable |
| MB90F548GL(S)-GE1 | Wider 3.5–5.5 V operating range, same 256 KB Flash, but only single CAN channel and 4 KB RAM | Not suitable for dual-bus architectures requiring simultaneous powertrain + body network access | Select for cost-sensitive 12 V battery-supplied modules where dual CAN is unnecessary |
Compared with MB90F549G(S)-GE1, CY90F546GPFR-GE1 provides 2 KB more RAM for larger CAN FIFOs and real-time task stacks; versus MB90F548GL(S)-GE1, it delivers essential dual-CAN capability required for OEM body control domain controllers.

FAQ
Does CY90F546GPFR-GE1 support J1939 protocol natively?
No hardware J1939 acceleration is present, but the dual FULL-CAN controllers fully comply with ISO 11898-1 V2.0B, enabling software implementation of J1939 data link layer. The 16-message buffer and flexible acceptance filtering simplify PGN filtering and priority-based transmission scheduling required by J1939.
What is the maximum baud rate supported by UART0 in synchronous mode?
UART0 supports synchronous communication up to 2 Mbps at 16 MHz system clock, using internal clock synchronization. This enables high-speed debug logging or bridging to SPI-based peripherals without external clock sources.
Can the Flash memory be programmed in-system without external high-voltage programming?
Yes - CY90F546GPFR-GE1 supports in-system programming (ISP) via on-chip algorithm commands (Write/Erase/Suspend/Resume) using standard VCC (4.5–5.5 V). No external VPP voltage is required for routine firmware updates.
Is the LQFP-100 package thermally enhanced?
Yes - the LQFP-100 package includes an exposed thermal pad on the bottom surface, electrically connected to VSS, enabling direct PCB copper pour attachment for improved heat dissipation in continuous 16 MHz operation at +105°C ambient.
