Product details
Overview
CY9AF1A2LPMC-G-UNE2 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 CPU frequency, 12-bit ADC (16 ch, 1.0 μs conversion), and 10-bit DAC (2 ch). 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 CY9AF1A2LPMC-G-UNE2 datasheet, CY9AF1A2LPMC-G-UNE2 pinout, CY9AF1A2LPMC-G-UNE2 application, or CY9AF1A2LPMC-G-UNE2 equivalent, key selection criteria include verified 1.8–5.5 V supply operation, 5 V-tolerant I/O support on selected pins, dual watchdog (HW/SW), and FM3 family peripheral compatibility per TYPE7 classification.
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: 4–20 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz internal CR oscillators, and configurable Main PLL.
The peripheral set includes eight base timers (PWM/PPG/reload/PWC), three 16-bit free-run timers, four input capture channels, six output compare units, and dedicated IGBT-mode functions (dead-time insertion, DTIF interrupt, DC chopper waveform generation) for real-time motor phase control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 20 MHz max operation - enables deterministic real-time task execution with hardware divide and Thumb-2 instruction set. |
| Flash Memory | 128 KB, 0-wait-state read - supports fast code execution without cache, with security lock for firmware IP protection. |
| SRAM | 16 KB on-chip, system bus-connected - provides low-latency data storage for control algorithms and interrupt service routines. |
| ADC | 12-bit SAR, 16 channels, 1.0 μs min conversion - delivers high-speed analog sensing for motor current/voltage feedback loops. |
| DAC | 10-bit R-2R, 2 channels - generates precise analog reference signals for sensor biasing or closed-loop actuator control. |

| Port Relocate Function | Runtime reassignment of peripheral functions (UART, CSIO, I²C, timers) to alternate GPIO pins - simplifies PCB layout and avoids signal congestion. |
| Dual Watchdog System | Independent hardware (CR-oscillator-clocked) and software watchdogs - ensures fail-safe recovery even during deep sleep or clock failure scenarios. |
| 5 V-Tolerant I/O | Selected pins withstand 5.5 V input while powered at 1.8–3.3 V - enables mixed-voltage system interfacing without external translators. |

FAQ
What is the maximum operating frequency and supported voltage range?
The CY9AF1A2LPMC-G-UNE2 operates up to 20 MHz and supports a wide supply range of 1.8 V to 5.5 V. This allows direct connection to both modern low-voltage logic and legacy 5 V systems. The core and I/O domains are internally regulated, and the 5 V-tolerant pins eliminate need for external level shifters in mixed-voltage designs.
Does this MCU support hardware-accelerated motor control functions?
Yes - it includes dedicated IGBT-mode peripherals: programmable dead-time insertion, DC chopper waveform generation, DTIF (motor emergency stop) interrupt, and A/D activation compare triggers. These features enable precise, cycle-accurate 3-phase inverter control without software overhead or external gate driver logic.
Is HDMI-CEC functionality fully integrated, including transmitter and receiver?
Yes - the MCU integrates complete HDMI-CEC protocol handling: receiver with SIRCS/NEC/HDMI-CEC mode selection and noise filtering, plus transmitter with automatic header block generation, arbitration loss detection, and ACK/EOM bit insertion. No external transceiver IC is required.
What debug interface and programming method does it use?
It uses Serial Wire JTAG Debug Port (SWJ-DP) compliant with Arm CoreSight standards. Programming and debugging are supported via standard SWD connectors and tools such as Segger J-Link or ST-Link v2 clones. Flash programming is performed through SWD without requiring bootloader code or special reset sequences.
