Product details
Overview
CY9AF112MAPMC-G-MNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, 80-pin LQFP package, 40 MHz max CPU frequency, and integrated motor control peripherals including 8-channel Base Timers, 2-unit Multi-function Timers, and QPRC for encoder position sensing - deployed in industrial motor drives and HVAC blower control systems.
For engineers reviewing the CY9AF112MAPMC-G-MNE2 datasheet, CY9AF112MAPMC-G-MNE2 pinout, CY9AF112MAPMC-G-MNE2 application, or CY9AF112MAPMC-G-MNE2 equivalent, key selection criteria include external bus interface support (25-bit address, 8-/16-bit data), LIN 2.1 compliance, dual watchdog timers (HW + SW), 12-bit ADC with 12 channels across 3 units, and SWJ-DP debug interface without ETM.
Technical Context
This FM3-series MCU implements a deterministic real-time execution environment via nested vectored interrupt controller (NVIC) with 48 peripheral interrupts and 16 priority levels, coupled with a 24-bit SysTick timer for OS task scheduling. Its memory subsystem separates instruction and data paths: SRAM0 (16 KB) connects to I-code/D-code buses, while SRAM1 (16 KB) resides on the system bus - enabling concurrent CPU and DMA access.
The peripheral architecture integrates time-critical motor functions: dual QPRC units track quadrature encoder signals with configurable AIN/BIN/ZIN edge detection; Base Timers support PWM/PPG/reload modes; and Multi-function Timers provide waveform generation, input capture, and A/D activation compare - all synchronized to a single clock domain derived from the main PLL or external oscillator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - delivers deterministic interrupt latency and Thumb-2 instruction efficiency for real-time embedded control. |
| Memory | 128 KB Flash (0 wait-state), 16 KB SRAM (split into SRAM0/SRAM1) - enables fast code execution and dual-bus data buffering for motor control algorithms. |
| ADC | 12-bit SAR, 12 channels across 3 units, 1.0 μs conversion @5 V - supports simultaneous sampling of current/voltage feedback in 3-phase inverters. |
| Timers | 8-channel Base Timer (PWM/PPG/reload), 2-unit MF-Timer (3×free-run, 4×input capture, 6×output compare), 2×QPRC - provides full encoder-based closed-loop motor control. |
| Communication | 8-channel multi-function serial interface (UART/CSIO/LIN/I2C), LIN 2.1 compliant, hardware flow control on ch.4 - enables robust communication with HVAC EC fans and automotive body controllers. |
| Power & Safety | 2.7–5.5 V supply, dual LVD (interrupt + reset), Clock Supervisor (CSV), dual watchdog (HW CR-oscillator + SW) - ensures fail-safe operation in industrial environments with voltage transients. |

Pinout & Package
Package: 80-pin LQFP (LQG080), 0.65 mm pitch, RoHS-compliant, surface-mount. Thermal pad not present. Standard JEDEC MO-207 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P09 | General-purpose I/O with trace/debug multiplexing | Support SWD debug (TCK/SWCLK, TMS/SWDIO, TDI, TDO/SWO) and trace clock/data - essential for development and field firmware updates. |
| P60–P63 | Serial interface and external bus signals | P60 = SIN5_0/TIOA2_2/INT15_1/MRDY_1 - enables UART receive, timer output, external interrupt, and ready handshake for NOR flash interfacing. |
| P20, P50–P51 | Motor control and analog inputs | P50 = INT00_0/AIN0_2/SIN3_1/RTO10_0 - serves as ADC channel 0 input, UART receive, and external interrupt source for emergency stop detection. |
| VCC, VSS (×4) | Power supply terminals | Dedicated power/ground pairs per quadrant reduce noise coupling - critical for stable ADC and timer operation in noisy motor drive environments. |
Key Features
| Feature | Design Value |
|---|---|
| Port Relocate Function | Permits dynamic assignment of peripheral functions (e.g., UART, LIN, PWM) to alternate GPIO pins - simplifies PCB layout and enables pin reuse across variants. |
| External Bus Interface | 8 chip selects, 25-bit address, 8-/16-bit data width - supports direct connection to external SRAM or NOR flash for bootloader storage or parameter logging. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 calculation - offloads integrity checks from CPU during firmware OTA updates or CAN/LIN message validation. |
| Low-Power Modes | SLEEP, TIMER, STOP - STOP mode disables CPU/core clocks while retaining SRAM content and wake-up capability via QPRC or external interrupt - extends battery life in portable HVAC controls. |
Applications
| Industrial Motor Drives | HVAC Blower Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Arm Cortex-M3 motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz Cortex-M3, 256 KB Flash, 48 KB SRAM, no QPRC, no LIN, 10-bit ADC | Lacks native LIN 2.1 and quadrature encoder counter - requires software emulation or external IC for HVAC fan control. | Select when higher CPU throughput and larger memory are needed, and LIN/QPRC can be implemented externally. |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB SRAM, no LIN, no QPRC, PIO for custom peripherals | No hardware LIN or QPRC; PIO must emulate encoder interface - increases firmware complexity and jitter. | Select for cost-sensitive consumer devices where flexibility outweighs real-time determinism and automotive protocol compliance. |
Compared with STM32F103VCT6 and RP2040, CY9AF112MAPMC-G-MNE2 delivers protocol-specific hardware acceleration (LIN 2.1, QPRC), deterministic motor control timing, and industrial-grade safety features (dual LVD, CSV) - making it optimal for certified HVAC and industrial motion systems where software emulation is unacceptable.

FAQ
Does CY9AF112MAPMC-G-MNE2 support external memory expansion?
Yes. It features an External Bus Interface with up to 8 chip selects, 25-bit address bus, and 8-/16-bit data bus - supporting direct connection to SRAM, NOR Flash, and other memory-mapped peripherals. This enables boot-from-external-flash configurations and runtime parameter logging without consuming internal Flash.
What debug interfaces does CY9AF112MAPMC-G-MNE2 provide?
It provides Serial Wire JTAG Debug Port (SWJ-DP) only - supporting standard SWD and JTAG protocols for programming and real-time debugging. Embedded Trace Macrocell (ETM) is not included, so instruction trace is unavailable; however, SWO (Serial Wire Output) enables printf-style debug logging via TDO pin.
Is hardware flow control supported on all UART channels?
No. Hardware flow control (CTS/RTS) is supported only on channel 4, as confirmed in the datasheet footnote. Channels 0–3 lack RTS/CTS signal routing - requiring software handshaking or external logic if full-duplex flow control is required on those channels.
How many ADC channels are available and what is their resolution?
CY9AF112MAPMC-G-MNE2 integrates three 12-bit successive approximation ADC units totaling 12 channels. Conversion time is 1.0 μs at 5 V supply, with built-in FIFO for scan-mode data storage (16-step depth) and priority-level selection for time-critical measurements like phase current sampling.
