Product details
Overview
CY9BF328SAPMC-GK7CGE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller in the FM3 family, operating up to 60 MHz with dual-bank flash (1.5 MB), 192 KB SRAM (SRAM0 + SRAM1), and integrated USB 2.0 Full-Speed Device/Host interface. It supports low-power modes including Deep Standby RTC and integrates 24-channel 12-bit ADC, 2-channel 10-bit DAC, and multi-protocol serial interfaces (UART/CSIO/LIN/I²C) for embedded motor control and industrial HMI applications.
For engineers reviewing the CY9BF328SAPMC-GK7CGE2 datasheet, CY9BF328SAPMC-GK7CGE2 pinout, CY9BF328SAPMC-GK7CGE2 application, or CY9BF328SAPMC-GK7CGE2 equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options aligned with Infineon's FM3 peripheral manual TYPE12 classification.
Technical Context
This MCU implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, coupled with a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem includes dual-operation Flash (ROM0/ROM1) enabling read-while-write operation and two independent SRAM banks-SRAM0 on I/D-code buses and SRAM1 on the system bus-for deterministic code/data access.
The peripheral set is optimized for real-time embedded control: quadrature position counters (QPRC) with AIN/BIN/ZIN edge configuration, HDMI-CEC/remote reception with automatic ACK, and a CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 for data integrity in communication and storage paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB9BF528RPMC-GK7CGE2 | Same FM3 platform, but with enhanced security features (AES engine, secure boot ROM) and extended temperature range (–40°C to +125°C). | Required for automotive body control modules needing ISO 26262 ASIL-B compliance and extended thermal operation. | Select when cryptographic acceleration or AEC-Q100 qualification is mandatory; otherwise, CY9BF328SAPMC-GK7CGE2 offers lower cost and identical peripheral set. |
| STM32F303VCT6 | Arm Cortex-M4F core, 72 MHz, 256 KB Flash, 48 KB SRAM, no native LIN or HDMI-CEC; adds FPU and advanced op-amps. | Suitable for analog-intensive signal conditioning but lacks hardware LIN/CEC - requires software stacks and external transceivers. | Choose only if floating-point math or analog front-end integration outweighs protocol offload benefits; adds ~$0.85 BOM cost and firmware complexity. |
Compared with MB9BF528RPMC-GK7CGE2 and STM32F303VCT6, CY9BF328SAPMC-GK7CGE2 delivers optimal balance of protocol hardware acceleration (LIN/CEC/USB), memory density, and industrial temperature support without security or FPU overhead - making it ideal for cost-sensitive, protocol-rich embedded controllers where deterministic peripheral response is prioritized over cryptographic or computational throughput.

FAQ
What is the maximum operating frequency and supported voltage range for CY9BF328SAPMC-GK7CGE2?
The CY9BF328SAPMC-GK7CGE2 operates at up to 60 MHz and supports a wide supply voltage range of 2.7 V to 5.5 V on VCC, with USBVCC requiring 3.0–3.6 V when USB functionality is active. This range enables direct interfacing with both 3.3 V and 5 V systems without level-shifting, and accommodates battery-powered designs down to 2.7 V while maintaining full peripheral functionality.
Does CY9BF328SAPMC-GK7CGE2 support LIN 2.1 protocol in hardware?
Yes, the CY9BF328SAPMC-GK7CGE2 includes dedicated LIN hardware in its multi-function serial interface channels, supporting LIN 2.1 specification including programmable break field (13–16 bits), break delimiter (1–4 bits), master/slave mode, and automatic checksum generation. No software stack or external transceiver is needed for basic LIN node implementation.
How many USB endpoints does CY9BF328SAPMC-GK7CGE2 support, and what transfer types are available?
The device supports six USB endpoints (EP0–EP5) in USB Device mode. EP0 handles control transfers only. EP1 supports Bulk, Interrupt, or Isochronous transfers with 256-byte buffer; EP2–EP5 support Bulk or Interrupt transfers with 64-byte buffers each. All endpoints feature double buffering to prevent data loss during host polling intervals.
Is there hardware support for CRC calculation, and which polynomials are implemented?
Yes, CY9BF328SAPMC-GK7CGE2 includes a dedicated CRC accelerator supporting CCITT CRC16 (polynomial 0x1021) and IEEE-802.3 CRC32 (polynomial 0x04C11DB7).
