Product details
Overview
CY9BF128SAPMC-GK7CGE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 1.5 MB dual-bank Flash, 192 KB SRAM (96 KB ×2), 60 MHz max CPU frequency, and integrated peripherals including 24-channel 12-bit ADC, 2-channel 10-bit DAC, 16-channel multi-function serial interface (UART/CSIO/LIN/I²C), and hardware CRC accelerator. It targets embedded motor control and industrial automation systems requiring low-power operation and real-time responsiveness.
For engineers reviewing the CY9BF128SAPMC-GK7CGE2 datasheet, CY9BF128SAPMC-GK7CGE2 pinout, CY9BF128SAPMC-GK7CGE2 application, or CY9BF128SAPMC-GK7CGE2 equivalent, key selection considerations include dual-bank Flash for safe firmware updates, 5V-tolerant GPIOs on select pins, deep-standby RTC mode with RAM retention, LIN 2.1 compliance, and SWJ-DP debug interface with ETM trace support.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem features dual-operation Flash enabling concurrent read/erase-critical for over-the-air (OTA) firmware updates without halting execution.
The peripheral set includes a 16-channel multi-function serial interface with per-channel mode selection (UART/CSIO/LIN/I²C), two independent A/D converters with 1.0 μs conversion time at 2.7–5.5 V, and a quadrature position/revolution counter (QPRC) with 16-bit position and revolution registers for encoder-based motion control.

FAQ
What is the maximum operating frequency and voltage range for CY9BF128SAPMC-GK7CGE2?
The CY9BF128SAPMC-GK7CGE2 operates at up to 60 MHz and supports a wide supply voltage range of 2.7 V to 5.5 V. This allows direct interfacing with both 3.3 V logic and legacy 5 V industrial sensors and actuators without level-shifting circuitry. The core and I/O domains share the same VCC rail, simplifying power design.
Does this MCU support over-the-air (OTA) firmware updates without service interruption?
Yes. Its dual-bank Flash architecture (1008 KB + 512 KB ROM1 + 16 KB ROM0 lower bank + 64 KB work area) enables true background programming: one bank runs active firmware while the other is erased, written, and verified. A software-triggered bank swap completes the update with sub-millisecond latency, meeting IEC 62443-3-3 requirements for secure field updates.
How many LIN 2.1 channels does CY9BF128SAPMC-GK7CGE2 support, and what features are included?
The MCU supports up to two LIN 2.1 channels via its multi-function serial interface. Each channel includes master/slave mode, programmable break field (13–16 bits), break delimiter (1–4 bits), automatic ACK reply, and full error detection (parity, framing, overrun). No external LIN transceiver is required for basic node functionality, though one is needed for bus physical layer compliance.
Is the Real-time Clock (RTC) functional in all low-power modes?
The RTC remains fully operational in SLEEP, TIMER, RTC, and Deep standby RTC modes, maintaining timekeeping using the 32.768 kHz sub-clock. It is disabled only in STOP and Deep standby STOP modes. In Deep standby RTC mode, RAM retention is optional-enabling either ultra-low-power timekeeping with minimal memory preservation or complete RAM shutdown for lowest leakage current.
