Product details
Overview
CY9AF112MPMC-G-MJE1 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, and integrated motor control peripherals including 8-channel Base Timers, 3-unit 12-bit ADC (16-channel total), and QPRC for encoder position sensing - deployed in industrial motor drives and HVAC blower control systems.
For engineers reviewing the CY9AF112MPMC-G-MJE1 datasheet, CY9AF112MPMC-G-MJE1 pinout, CY9AF112MPMC-G-MJE1 application, or CY9AF112MPMC-G-MJE1 equivalent, key selection criteria include external bus interface support (25-bit address, 8-/16-bit data, 8 chip selects), dual watchdog timers (HW + SW), CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), and 16-channel A/D conversion at 1.0 μs @5 V.
Technical Context
The CY9AF112MPMC-G-MJE1 implements an Arm Cortex-M3 r2p1 core operating up to 40 MHz with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem features zero-wait-state Flash and dual-bus-connected SRAM banks (SRAM0 on I-code/D-code buses, SRAM1 on system bus) enabling concurrent CPU and DMA access.
Peripherals include 8-channel multi-function serial interfaces (4 with 16×9-bit FIFO), LIN 2.1-compliant transceivers, hardware flow control on UART ch.4, and a dedicated DMA controller with 8 channels supporting burst/block/demand transfers across 4 GB address space - all coordinated via port relocation logic for flexible pin assignment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time control with low-latency interrupt handling. |
| Flash Memory | 256 KB, 0 wait-state read - supports fast code execution without cache penalties in cost-sensitive motor control firmware. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1) - dual-bank architecture allows simultaneous CPU instruction fetch and DMA data transfer. |
| A/D Converter | 12-bit SAR, 16 channels, 1.0 μs conversion @5 V - meets timing requirements for current sensing and analog feedback in PMSM/BLDC drives. |
| External Bus Interface | 25-bit address, 8-/16-bit data, 8 chip selects - enables direct connection to external NOR Flash or SRAM for firmware expansion or data logging. |
| Debug Interface | Serial Wire JTAG Debug Port (SWJ-DP) - provides full debug visibility without requiring dedicated JTAG pins, reducing PCB footprint. |
| Power Supply | 2.7 V to 5.5 V operation - supports direct interface with 3.3 V or 5 V industrial I/O rails without level-shifting. |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|

| CRC Acceleration | Hardware CCITT CRC16 and IEEE-802.3 CRC32 engines - offloads integrity checking from CPU during firmware updates or CAN/LIN message validation. |
| Dual Watchdog System | Independent HW watchdog (low-speed CR oscillator) and SW watchdog - ensures fail-safe recovery even during deep sleep modes where main clock is stopped. |
| Port Relocation Logic | EPFR-based function assignment across multiple pins per peripheral channel - decouples hardware layout from firmware-defined peripheral mapping, accelerating board reuse. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz, 256 KB Flash, 48 KB SRAM, no external bus interface, integrated op-amps/comparators. | Lacks external memory expansion capability; better suited for analog-intensive sensor fusion than external device interfacing. | Select when high-precision analog signal conditioning is required over external memory bandwidth. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4 core, 48 MHz, 256 KB Flash, 32 KB SRAM, no QPRC, includes USB FS, TrustZone security. | No quadrature encoder counter; adds USB connectivity and hardware crypto acceleration but removes motor-specific timing peripherals. | Select when USB device functionality or secure boot is prioritized over encoder-based position control. |
Compared with STM32F303VCT6 and RA4M1, the CY9AF112MPMC-G-MJE1 uniquely combines external bus support, dual-bank SRAM for concurrent access, and dedicated QPRC - making it optimal for cost-constrained industrial drives requiring external memory and high-resolution encoder feedback without sacrificing real-time determinism.

FAQ
Does CY9AF112MPMC-G-MJE1 support hardware flow control on UART?
No. Hardware flow control (CTS/RTS) is explicitly excluded for CY9AF112LA, F112L, and related variants per the official datasheet (Rev. *H, page 2). Only UART channel 4 supports this feature in higher-tier models like CY9AF114LA. The CY9AF112MPMC-G-MJE1 uses software handshaking or buffer management instead.
What is the maximum operating frequency of the main PLL?
The main PLL supports output frequencies up to 40 MHz, matching the maximum CPU clock rate. It accepts input clocks from 4 MHz to 48 MHz external oscillators or the 4 MHz built-in high-speed CR oscillator, with programmable multiplication/division ratios defined in the system control registers.
Is the 100-pin LQFP package RoHS compliant and lead-free?
Yes. The LQI100 package used for CY9AF112MPMC-G-MJE1 meets RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking standards for lead-free solderability, with matte tin finish and halogen-free molding compound per Infineon's material declarations.
Can the CRC accelerator compute custom polynomials beyond CCITT CRC16 and IEEE-802.3 CRC32?
No. The hardware CRC accelerator is fixed-function and only supports the two generator polynomials specified in the datasheet: 0x1021 for CCITT CRC16 and 0x04C11DB7 for IEEE-802.3 CRC32. Custom polynomial computation must be performed in software using the general-purpose ALU.
