Overview
CY9AF1A2NPMC-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 CY9AF1A2NPMC-G-UNE2 datasheet, CY9AF1A2NPMC-G-UNE2 pinout, CY9AF1A2NPMC-G-UNE2 application, or CY9AF1A2NPMC-G-UNE2 equivalent, key selection criteria include Flash/SRAM size, 12-bit ADC timing, dual DAC resolution, RTC calendar accuracy, and IGBT-mode PWM dead-time support for real-time motor control firmware development.
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 dual-stage Low-Voltage Detection (LVD1/LVD2).
The peripheral set includes eight base timers (configurable as 16-/32-bit PWM, PPG, reload, or PWC), multi-function serial interfaces (up to 8 channels, UART/CSIO/I²C), and dedicated motor control blocks: DC chopper waveform generation, DTIF emergency stop interrupt, and A/D activation compare triggers synchronized to PWM cycles.
Key Specifications

FAQ
What is the maximum operating frequency and core version of CY9AF1A2NPMC-G-UNE2?
The CY9AF1A2NPMC-G-UNE2 operates at up to 20 MHz and uses the Arm Cortex-M3 processor core revision r2p1. This core includes a Nested Vectored Interrupt Controller (NVIC) with 32 peripheral interrupt channels and 8 priority levels, plus a 24-bit SysTick timer for OS task scheduling. The 20 MHz limit reflects its optimization for ultra-low-power embedded control rather than high-throughput computation.
Does CY9AF1A2NPMC-G-UNE2 support hardware-accelerated motor control features?
Yes - it includes dedicated IGBT-mode PWM blocks with programmable dead-time insertion, DC chopper waveform generation, A/D activation compare triggers synchronized to PWM edges, and DTIF (motor emergency stop) interrupt capability. These features enable safe, real-time motor gate driving without external logic or software overhead, verified in Infineon's FM3 Peripheral Manual TYPE7 configuration.
Can CY9AF1A2NPMC-G-UNE2 operate from a single 3.3 V supply?
Yes - the device supports a wide VCC range of 1.8 V to 5.5 V, making it compatible with standard 3.3 V logic systems. All I/O pins are 5 V tolerant on designated ports, allowing direct interfacing with legacy 5 V peripherals without level-shifting circuitry, as confirmed in the "I/O Circuit Type" section of the datasheet (Rev. *F, page 30).
Is the RTC in CY9AF1A2NPMC-G-UNE2 battery-backed and does it support leap-year calculation?
Yes - the RTC maintains full calendar functionality (Year/Month/Day/Hour/Minute/Second/Weekday) with automatic leap-year compensation and continues counting during Deep Standby RTC mode using the 32.768 kHz sub-clock. It retains time across power cycles when backed by a coin cell on VBAT, and supports alarm interrupts down to minute-level granularity.
