Infineon Technologies CY90F548GSPMC-GE1

Overview

CY90F548GSPMC-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. It operates at up to 16 MHz system clock (via on-chip PLL ×4), achieves 62.5 ns minimum instruction execution time, and targets automotive body control modules requiring CAN-based distributed networking and real-time I/O management.

For engineers reviewing the CY90F548GSPMC-GE1 datasheet, CY90F548GSPMC-GE1 pinout, CY90F548GSPMC-GE1 application, or CY90F548GSPMC-GE1 equivalent, key selection criteria include dual-CAN channel support, 8/10-bit 8-channel ADC with 26.3 µs conversion time, programmable pulse generation (PPG), and Flash memory block protection with 10,000 erase cycles.

Technical Context

The CY90F548GSPMC-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. Its interrupt subsystem supports 8 priority levels and 34 sources, including delayed-interrupt generation for task switching.

Dual FULL-CAN controllers provide flexible mailbox/FIFO buffering, automatic retransmission, remote frame response, and acceptance filtering (full-bit compare/mask or two partial masks). The external bus interface supports up to 16 MB address space with 8-/16-bit data width selection.

FAQ

What is the maximum CAN bit rate supported by CY90F548GSPMC-GE1?

The device supports CAN communication up to 1 Mbps, compliant with ISO 11898-1 (CAN 2.0A/B). This maximum rate is achievable with proper bus termination, transceiver selection, and cable length ≤ 40 m. Bit timing registers allow fine-tuning of synchronization segments and propagation delays to maintain robustness under electromagnetic interference.

Does CY90F548GSPMC-GE1 support in-system programming (ISP) of Flash memory?

Yes, it supports ISP via on-chip bootloader using UART0 or UART1. Flash programming requires external 12 V Vpp for block protection unlock, and erase/write operations are controlled by embedded algorithm commands (Erase-Suspend/Resume). Completion is signaled via dedicated status flag, enabling safe firmware updates without external programmers.

How many general-purpose I/O pins does CY90F548GSPMC-GE1 provide?

The device provides 81 programmable general-purpose I/O ports, all configurable as push-pull outputs or Schmitt-trigger inputs. Each port supports bit-wise direction control and can be reassigned to alternate peripheral functions (e.g., UART, CAN, ADC) via register settings. Port pins P00–P07, P10–P17, P50–P57, P60–P67, P70–P77, P80–P87, and P90–P97 constitute the full set.

Is the 32 kHz sub-clock source internal or external?

The 32 kHz sub-clock is generated externally using a dedicated 32.768 kHz crystal connected to X0/X1 pins. This low-frequency clock drives sleep-mode timers and RTC functions while minimizing power consumption. The sub-clock circuit includes built-in oscillator startup stabilization and failure detection logic to ensure reliable low-power operation.
