Product details
Overview
CY9AF112MPMC-GE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 256 KB on-chip Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), 100-pin LQFP package, 40 MHz max operation, and integrated motor control peripherals including 8-channel Base Timers, 2-unit Multi-function Timers, QPRC, and LIN 2.1 support - deployed in industrial motor drives and HVAC blower control systems.
For engineers reviewing the CY9AF112MPMC-GE1 datasheet, CY9AF112MPMC-GE1 pinout, CY9AF112MPMC-GE1 application, or CY9AF112MPMC-GE1 equivalent, key selection criteria include Flash/SRAM allocation, 100-pin LQFP package compatibility, LIN/UART/CSIO serial interface count, 16-channel 12-bit ADC timing, and external bus interface support for NOR Flash expansion.
Technical Context
The device implements a dual-bus SRAM architecture: SRAM0 (16 KB) connects to I-code and D-code buses for low-latency instruction/data access, while SRAM1 (16 KB) connects to the system bus for DMA-peripheral transfers. Its NVIC supports 48 peripheral interrupts across 16 priority levels, with dedicated SysTick for RTOS scheduling.
Peripheral integration centers on deterministic real-time control: 8-channel Base Timers support PWM/PPG/reload modes; two Multi-function Timer units provide 6 output compare channels each, A/D activation triggers, and waveform generation; QPRC units accept quadrature A/B/Z inputs for position feedback in closed-loop motor systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic interrupt latency & RTOS execution in motion control loops |
| Flash Memory | 256 KB, 0-wait-state read - supports fast code execution without cache penalties in compact firmware images |

Does CY9AF112MPMC-GE1 support hardware LIN 2.1 communication?
Yes, CY9AF112MPMC-GE1 integrates a dedicated LIN controller supporting LIN protocol revision 2.1 in both master and slave modes. It provides hardware break field generation (13–16 bit), break delimiter (1–4 bit), full-duplex double buffering, and automatic error detection (parity, framing, overrun) - eliminating need for external LIN transceivers in compliant nodes.
How many ADC channels and what resolution does the device offer?
CY9AF112MPMC-GE1 includes three 12-bit successive approximation ADC units totaling 16 input channels. Conversion time is 1.0 μs at 5 V supply. It supports scanning mode with 16-step FIFO and priority conversion with 4-step FIFO, plus hardware-triggered sampling via A/D activation compare from timer outputs - critical for synchronized current sensing in motor control.
Is external memory expansion supported, and what interfaces are available?
Yes, CY9AF112MPMC-GE1 supports external memory expansion via its External Bus Interface (EBI), which provides up to 8 chip selects, 8-/16-bit data width, and up to 25-bit addressing (256 MB address space).
