Infineon Technologies CY9AFAA2NPMC-G-SNE2

Overview

CY9AFAA2NPMC-G-SNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, and integrated LCD controller (44 SEG × 4 COM), 16-channel 12-bit ADC (1.0 µs min conversion), and dual 10-bit DACs-designed for low-power embedded motor control and industrial HMI applications.

For engineers reviewing the CY9AFAA2NPMC-G-SNE2 datasheet, CY9AFAA2NPMC-G-SNE2 pinout, CY9AFAA2NPMC-G-SNE2 application, or CY9AFAA2NPMC-G-SNE2 equivalent, key selection criteria include its 20 MHz max operating frequency, RTC with leap-year support, HDMI-CEC/remote receiver (2 channels), and 100-pin LQFP package with 84 high-speed GPIOs and 5V-tolerant pins.

Technical Context

The device implements a full Arm Cortex-M3 r2p1 core with NVIC supporting 32 peripheral interrupts and 8 priority levels, plus a 24-bit SysTick timer for RTOS integration. It integrates dual watchdog timers-one hardware-based on a 100 kHz CR oscillator active in all low-power modes except Deep Standby RTC/Stop-and Clock Supervision (CSV) to detect external clock failure or frequency anomaly via internal CR oscillators.

Its peripheral set includes up to eight multi-function serial interfaces (UART/CSIO/I²C), eight base timers (16-/32-bit PWM/PPG/reload/PWC), and a dedicated multi-function timer block with input capture (4ch), output compare (6ch), A/D activation compare (1ch), and waveform generation (3ch) for motor control timing precision.

FAQ

What is the maximum operating frequency and core revision of CY9AFAA2NPMC-G-SNE2?

The CY9AFAA2NPMC-G-SNE2 operates at up to 20 MHz and uses the Arm Cortex-M3 processor revision r2p1. This revision supports the full Thumb-2 instruction set, NVIC with 32 peripheral interrupt lines, and 8 priority levels-enabling deterministic real-time task scheduling in embedded control applications.

Does this MCU support hardware-accelerated HDMI-CEC communication?

Yes, CY9AFAA2NPMC-G-SNE2 includes two dedicated HDMI-CEC/remote control receiver channels with hardware protocol decoding for SIRCS, NEC, and HDMI-CEC standards. It provides automatic header transmission, arbitration loss detection, and START/EOM/ACK generation-offloading full CEC frame handling from the CPU.

What low-power modes are supported, and which retain RTC functionality?

The MCU supports six low-power modes: Sleep, Timer, RTC, Stop, Deep Standby RTC, and Deep Standby Stop. Only Deep Standby RTC and Deep Standby Stop retain RTC operation with calendar timekeeping and alarm wake-up capability, drawing less than 1 µA while preserving the 16-byte backup register.

Is the LCD controller capable of driving common-anode or common-cathode displays?

The integrated LCD controller supports both common-anode and common-cathode configurations via software-selectable bias polarity. It delivers up to 44 segments and 8 commons, with internal resistor networks (10 kΩ or 100 kΩ) and dedicated VV0–VV4 bias supply pins-enabling direct drive of passive segment LCDs without external components.
