Product details
Overview
CY9AFAA1NPMC-G-UNE2 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 supporting up to 44×4 SEG/COM. It operates at up to 20 MHz, features dual 10-bit DACs, 16-channel 12-bit ADC, and hardware watchdog timers. Used in industrial HMI panels requiring low-power operation and embedded motor control.
For engineers reviewing the CY9AFAA1NPMC-G-UNE2 datasheet, CY9AFAA1NPMC-G-UNE2 pinout, CY9AFAA1NPMC-G-UNE2 application, or CY9AFAA1NPMC-G-UNE2 equivalent, key selection criteria include LCD drive capability (VV0–VV4 bias pins), 5V-tolerant I/O count (up to 84 ports), RTC with leap-year support, HDMI-CEC/remote receiver dual-mode operation, and six low-power modes including Deep Standby RTC.
Technical Context
The CY9AFAA1NPMC-G-UNE2 implements an 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 integrates five sources: 4–20 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz internal CR oscillators, and a configurable Main PLL.
Peripheral integration includes eight base timers (PWM/PPG/reload/PWC), three 16-bit free-run timers, four input capture channels, six output compare units, and motor-control-specific functions: dead-time insertion, DTIF emergency stop interrupt, and DC chopper waveform generation.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz Cortex-M3, 256 KB Flash, no integrated LCD controller, no HDMI-CEC receiver | Requires external LCD driver and IR demodulator IC; higher performance but larger BOM | Choose when higher CPU throughput and USB connectivity are required over integrated display/remote control. |

FAQ
What is the maximum operating frequency and supported voltage range?
The CY9AFAA1NPMC-G-UNE2 operates at up to 20 MHz and supports a wide supply range of 1.8 V to 5.5 V. When the LCD controller is active, the minimum VCC is 2.2 V. All DC and AC characteristics-including Flash read timing and ADC conversion-are guaranteed across this full voltage and temperature range per datasheet Rev. *F.
Does this MCU support debug interfaces, and which ones are available?
Yes, it features a Serial Wire JTAG Debug Port (SWJ-DP) supporting both SWD and JTAG protocols. This allows full-cycle debugging, flash programming, and real-time trace without halting CPU execution. The interface remains functional in all operational and low-power modes except Deep Standby Stop.
How many I/O pins are 5V tolerant, and how is this verified?
Selected GPIO pins-including PA0–PA7, PB0–PB7, and PC0–PC7-are explicitly rated as 5V tolerant per Section 11.3.2 of the datasheet. Tolerance is ensured by internal clamping diodes and verified under recommended operating conditions (VCC ≥ 2.2 V) with absolute maximum rating of 6.0 V on those pins.
Can the RTC retain time during Deep Standby RTC mode, and what power source is used?
Yes, the RTC continues counting in Deep Standby RTC mode using the 32.768 kHz crystal connected to RTC_XIN/RTC_XOUT. Only the RTC block and 16-byte backup register remain powered; total current draw is less than 1 µA. Leap-year calculation and alarm interrupts remain fully functional.
