Product details
Overview
CY9AF1A2NPF-G-SNE1 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 channels, 1.0 μs conversion), and dual 10-bit DACs. 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 CY9AF1A2NPF-G-SNE1 datasheet, CY9AF1A2NPF-G-SNE1 pinout, CY9AF1A2NPF-G-SNE1 application, or CY9AF1A2NPF-G-SNE1 equivalent, key selection criteria include Flash/SRAM size, 12-bit ADC timing, 100-pin LQFP package compatibility, IGBT-mode PWM support, and dual watchdog timer architecture for safety-critical firmware.
Technical Context
The device 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 combines five sources - including 4–20 MHz main oscillator, 32.768 kHz sub-clock, and dual CR oscillators - supervised by Clock Supervision (CSV) and Low-Voltage Detector (LVD) with two independent reset thresholds.
Peripheral integration includes eight base timers (configurable as 16-/32-bit PWM, PPG, reload, or PWC), multi-function serial interface (up to 8 channels supporting UART/CSIO/I²C), and dedicated motor control features: dead-time insertion, DTIF emergency stop interrupt, and A/D activation compare triggers synchronized to PWM cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, enabling deterministic interrupt latency and Thumb-2 instruction efficiency for real-time control loops. |
| Max Operating Frequency | 20 MHz - defines maximum instruction throughput and peripheral timing margins for motor control PWM generation. |
| Flash Memory | 128 KB with zero-wait-state read - supports fast code execution and firmware update partitioning without performance penalty. |
| SRAM | 16 KB on-chip, directly connected to System bus - sufficient for stack, heap, and real-time data buffers in closed-loop control. |
| ADC | 12-bit SAR, 16-channel, 1.0 μs min conversion - enables high-resolution current/voltage sampling in servo drive feedback paths. |
| DAC | Two 10-bit R-2R DACs - provide analog setpoint or bias voltage generation for sensor calibration or reference circuits. |
| Low-Power Modes | Six modes including Deep Standby RTC - allows battery-backed timekeeping with <1 μA retention current while preserving 16-byte backup registers. |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, with 84 high-speed GPIOs (some 5 V tolerant) and dedicated power/ground pins for noise-sensitive analog sections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dedicated analog/digital power domains with separate pins - enables PCB-level separation of noisy digital switching from precision ADC/DAC reference paths. |
| XTAL1 / XTAL2 | Main crystal oscillator input/output | Supports 4–20 MHz external crystals - provides stable, low-jitter clock source for precise PWM timing and communication baud rate accuracy. |
| RTC_XIN / RTC_XOUT | Real-time clock crystal interface | Connects to 32.768 kHz tuning-fork crystal - maintains calendar time during Deep Standby modes with ultra-low leakage. |
| PA0–PA15, PB0–PB15, etc. | Multi-function GPIO ports | Port relocate function allows dynamic assignment of UART/I²C/ADC functions to any compatible pin - simplifies PCB layout and enables pin-compatible firmware variants. |
| AD0–AD15 | Analog input channels | 16 dedicated ADC input pins with internal sample-and-hold - eliminates need for external multiplexers in multi-sensor monitoring applications. |
| DA0 / DA1 | Analog output terminals | Direct R-2R DAC outputs - deliver rail-to-rail analog voltages without external op-amp buffering for calibration or biasing tasks. |
Key Features
| Feature | Design Value |
|---|---|
| IGBT Mode PWM | Integrated dead-time insertion, DTIF emergency stop interrupt, and A/D activation compare - enables safe, synchronized gate driving for 3-phase inverter stages. |
| HDMI-CEC Transceiver | Full CEC protocol stack hardware: automatic header transmission, arbitration loss detection, START/EOM/ACK generation - reduces MCU firmware overhead in smart appliance remote control subsystems. |
| Motor Control Timers | Eight base timers configurable as 16-/32-bit PWM, PPG, or reload units - supports complex waveform generation (e.g., sinusoidal commutation) with minimal CPU intervention. |
| SWJ-DP Debug Port | Serial Wire JTAG interface with full SWD support - permits non-intrusive real-time debugging and flash programming without requiring dedicated debug pins beyond SWDIO/SWCLK. |
| Backup Register | 16 bytes retained across all low-power modes - stores critical calibration coefficients or fault history during extended power-loss events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | ARM Cortex-M3 @ 72 MHz, 256 KB Flash, 48 KB RAM, no integrated HDMI-CEC or IGBT-mode PWM. | Lacks hardware CEC and motor-specific dead-time control - requires software emulation or external logic for similar functionality. | Choose when higher clock speed and larger memory are prioritized over integrated motor control and remote control features. |
| RL78/G14 R5F104PJSP | 16-bit RL78 core, 128 KB Flash, 12 KB RAM, 10-bit ADC, no Cortex-M3 ISA or SWJ-DP debug port. | Lower performance and no Thumb-2 compatibility - limits portability of existing Cortex-based firmware stacks. | Prefer for ultra-low-power (<0.5 μA Stop mode) legacy designs where 32-bit performance and modern toolchain support are secondary. |
Compared with STM32F103VCT6 and RL78/G14 R5F104PJSP, CY9AF1A2NPF-G-SNE1 uniquely delivers HDMI-CEC transceiver hardware, IGBT-mode PWM with DTIF, and 12-bit ADC timing optimized for motor current sampling - making it the only option among the three that satisfies concurrent real-time control, remote interface, and precision analog requirements in single-chip implementations.

FAQ
What power supply voltage range does CY9AF1A2NPF-G-SNE1 support?
The device operates across a wide VCC range of 1.8 V to 5.5 V, enabling direct interface with both 3.3 V logic systems and legacy 5 V peripherals without level-shifting. This range accommodates varying board-level power architectures and simplifies design reuse across multiple product generations.
Does CY9AF1A2NPF-G-SNE1 include hardware support for motor control PWM dead-time insertion?
Yes - the IGBT mode includes dedicated hardware dead-time insertion, DTIF (motor emergency stop) interrupt, and A/D activation compare triggers synchronized to PWM edges. These features eliminate software timing dependencies and ensure safe, glitch-free gate driver switching in inverter applications.
Can the CY9AF1A2NPF-G-SNE1 operate in deep sleep modes while maintaining RTC functionality?
Yes - Deep Standby RTC mode retains RTC operation and 16-byte backup register contents with typical current consumption below 1 μA, powered solely by VBAT. The 32.768 kHz RTC crystal continues running, enabling calendar timekeeping and alarm wake-up without main VCC.
Is the HDMI-CEC interface fully hardware-implemented or firmware-dependent?
The HDMI-CEC interface is fully hardware-accelerated: it handles START/EOM/ACK bit generation, arbitration loss detection, and header transmission automatically. Firmware only configures registers and responds to status interrupts - no bit-banging or timing-critical software routines are required.
