Product details
Overview
CY9AF1A2MPMC1-G-SNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, 20 MHz max operating frequency, 12-bit ADC (16 channels, 1.0 μs conversion), and dual 10-bit DACs. It integrates motor control timers, UART/CSIO/I²C interfaces, RTC, HDMI-CEC receiver/transmitter, and six low-power modes - deployed in industrial motor drives and embedded control systems.
For engineers reviewing the CY9AF1A2MPMC1-G-SNE2 datasheet, CY9AF1A2MPMC1-G-SNE2 pinout, CY9AF1A2MPMC1-G-SNE2 application, or CY9AF1A2MPMC1-G-SNE2 equivalent, key selection criteria include Flash/SRAM size, 12-bit ADC timing, 100-pin LQFP package compatibility, IGBT-mode PWM support, and dual watchdog timer architecture for safety-critical firmware.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with NVIC supporting 32 peripheral interrupts and 8 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its clock system combines five sources - including 4–20 MHz main oscillator, 32.768 kHz sub-clock, and dual CR oscillators - supervised by Clock Supervision (CSV) and Low-Voltage Detection (LVD1/LVD2).
The peripheral set includes eight base timers (configurable as 16-/32-bit reload, PWM, PPG, or PWC), multi-function serial interfaces (up to 8 channels, UART/CSIO/I²C), and dedicated motor control features: dead-time insertion, DTIF emergency stop interrupt, and A/D activation compare for synchronized sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M3 r2p1, enabling deterministic interrupt latency and Thumb-2 instruction efficiency for real-time control loops |
| Max Frequency | 20 MHz - defines maximum instruction throughput and peripheral timing margins in closed-loop motor control |
| Flash Memory | 128 KB with 0-wait-state read - supports fast ISR execution and firmware over-the-air update partitioning |
| SRAM | 16 KB on-chip, directly connected to System bus - sufficient for stack, heap, and real-time data buffers without external memory |
| ADC | 12-bit SAR, 16-channel, 1.0 μs conversion - enables high-fidelity current/voltage sensing in 3-phase inverter feedback |
| DAC | Two 10-bit R-2R DACs - provide analog reference outputs for biasing, calibration, or sensor excitation |
| Low-Power Modes | Six modes including Deep Standby RTC - allows <1 μA retention current while maintaining calendar time and wake-up capability |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, with 84 high-speed GPIOs (some 5 V tolerant) and dedicated power/ground pins for noise isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual VCC/VSS pairs per side ensure stable core and I/O rail decoupling; separate analog/digital ground pins reduce coupling noise |
| XTAL / EXTAL | Main clock input/output | Accepts 4–20 MHz crystal or external clock - primary timing source for PLL, CPU, and high-speed peripherals |
| RTCXTAL / RTCXTAL | Sub-clock input | Connects 32.768 kHz crystal for RTC operation during Stop/Deep Standby modes |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO | Configurable per-port relocate function - allows flexible PCB layout by remapping UART, PWM, or ADC inputs to alternate pins |
| AD0–AD15 | Analog input | Dedicated 12-bit ADC channel inputs - routed internally to sample-and-hold circuit with FIFO buffering for scan mode |
| DA0 / DA1 | Analog output | 10-bit R-2R DAC outputs - deliver calibrated voltage references independent of VCC fluctuations |
Key Features
| Feature | Design Value |
|---|---|
| IGBT-mode PWM | Integrated dead-time insertion, DTIF emergency stop interrupt, and A/D activation compare - enables safe, synchronized gate driving in motor inverters |
| HDMI-CEC Interface | Full CEC transmitter/receiver with automatic header block generation, arbitration loss detection, and noise-filtered SIRCS/NEC decoding - supports consumer appliance remote interoperability |
| Real-Time Clock | Calendar counter (Year/Month/Day/Hour/Minute/Second/Weekday) with leap-year correction and date/time-match interrupt - eliminates need for external RTC IC |
| Watchdog Architecture | Dual watchdogs: hardware WD (clocked by 100 kHz CR oscillator, active in all low-power modes except Deep Standby) and software WD - provides layered fault recovery |
| Port Relocate Function | Peripheral function assignment to GPIO ports configurable via register - simplifies routing in dense 100-pin LQFP layouts without redesign |
Applications
| Industrial Motor Control | Smart Appliance Remote Interface |
|---|---|
Use Scenario: Closed-loop speed/torque control of BLDC or PMSM motors in HVAC blowers and pump drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103C8T6 | ARM Cortex-M3, 64 KB Flash, 20 KB RAM, no integrated HDMI-CEC or IGBT-mode PWM; 72 MHz max clock | Lacks native CEC transceiver and motor-specific dead-time hardware - requires software emulation or external logic | Select when higher CPU performance is prioritized over integrated motor control peripherals and remote interface functions |
| RP2040 | Dual-core ARM Cortex-M0+, 2 MB Flash, 264 KB RAM, no hardware RTC or LVD; USB host/device supported | No built-in LVD, CSV, or deep-standby RTC - unsuitable for battery-backed calendar applications or safety-monitored power rails | Select for cost-sensitive, USB-connected IoT endpoints where rich connectivity outweighs analog/motor control integration |
Compared with STM32F103C8T6 and RP2040, CY9AF1A2MPMC1-G-SNE2 delivers unique value in embedded motor control and appliance remote management through its hardware-accelerated IGBT-mode PWM, full HDMI-CEC stack, and ultra-low-power RTC - reducing BOM count and firmware complexity in industrial and white-goods designs.

FAQ
What is the maximum operating voltage range for CY9AF1A2MPMC1-G-SNE2?
The device operates across a wide VCC range of 1.8 V to 5.5 V, enabling direct interfacing with both 3.3 V logic and legacy 5 V systems without level shifters. This flexibility supports mixed-voltage board designs and simplifies power architecture in appliances with diverse sensor and actuator interfaces.
Does CY9AF1A2MPMC1-G-SNE2 support debug via SWD or JTAG?
Yes, it features a Serial Wire JTAG Debug Port (SWJ-DP) compliant with Arm CoreSight standards, allowing full-cycle debugging, flash programming, and real-time trace using standard tools like Segger J-Link or ST-Link v2.1 adapters - no external debug probe required beyond standard SWD headers.
How many independent PWM outputs does this MCU provide?
The MCU offers up to eight base timer channels, each configurable as 16-bit PWM, PPG, reload, or PWC timers. In IGBT-mode, two complementary PWM outputs with programmable dead-time can be generated per channel - supporting up to four independent half-bridge drivers with hardware-synchronized timing.
Is the RTC battery-backed, and what is its lowest power consumption mode?
Yes, the RTC retains time in Deep Standby RTC mode with typical current draw below 1 μA using an external backup battery or supercapacitor on VBAT. It maintains full calendar functionality (year/month/day/hour/minute/second/weekday) and supports wake-up interrupts - eliminating need for external RTC chips in battery-powered applications.
