Infineon Technologies CY9AF1A1NPMC-G-SNE2

Overview

CY9AF1A1NPMC-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 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 CY9AF1A1NPMC-G-SNE2 datasheet, CY9AF1A1NPMC-G-SNE2 pinout, CY9AF1A1NPMC-G-SNE2 application, or CY9AF1A1NPMC-G-SNE2 equivalent, key selection criteria include Flash/SRAM size, 12-bit ADC timing, dual DAC support, IGBT-mode PWM features, and 1.8–5.5 V supply range for mixed-voltage system integration.

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) for fail-safe operation.

The peripheral set includes eight base timers (configurable as PWM/PPG/reload/PWC), multi-function serial interfaces (up to 8 channels, UART/CSIO/I²C), and dedicated motor control blocks: dead-time insertion, DTIF emergency stop interrupt, and A/D activation compare for synchronized sampling.

FAQ

What is the maximum operating frequency and core revision of CY9AF1A1NPMC-G-SNE2?

The CY9AF1A1NPMC-G-SNE2 operates at up to 20 MHz and implements the Arm Cortex-M3 processor revision r2p1. This revision includes full Thumb-2 instruction support, hardware integer divide, and the Nested Vectored Interrupt Controller (NVIC) with 32 peripheral interrupt channels and 8 priority levels - confirmed in the official Infineon FM3 Peripheral Manual and datasheet Rev. *F.

Does this MCU support HDMI-CEC protocol natively, and what functions are integrated?

Yes - it integrates a full HDMI-CEC transceiver with both receiver and transmitter functionality. The receiver supports SIRCS, NEC, and HDMI-CEC standards with adjustable bit timing and noise filtering; the transmitter handles header block auto-generation, arbitration loss detection, and automatic START/EOM/ACK signaling - all implemented in hardware without firmware overhead.

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

Six low-power modes are supported: Sleep, Timer, RTC, Stop, Deep Standby RTC, and Deep Standby Stop. Only RTC, Deep Standby RTC, and Deep Standby Stop retain RTC operation and the 16-byte backup register. In Deep Standby RTC mode, current consumption drops below 1 μA while maintaining calendar time and wake-up capability via RTC alarm.

Is the 100-pin LQFP package RoHS-compliant and what is its moisture sensitivity level?

Yes - the CY9AF1A1NPMC-G-SNE2 uses a RoHS-compliant 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with Moisture Sensitivity Level 3 (MSL-3), requiring bake conditioning if exposed to ambient conditions beyond 168 hours before reflow soldering per J-STD-020.
