Product details
Overview
CY9AFAA2LPMC1-G-UNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller in the FM3 family, designed for embedded motor control and industrial HMI applications. It operates up to 20 MHz, integrates 128 KB flash and 16 KB SRAM, features an LCD controller (44×4 SEG/COM), dual 10-bit DACs, 16-channel 12-bit ADC with 1.0 µs conversion time, and supports UART/CSIO/I²C interfaces.
For engineers reviewing the CY9AFAA2LPMC1-G-UNE2 datasheet, CY9AFAA2LPMC1-G-UNE2 pinout, CY9AFAA2LPMC1-G-UNE2 application, or CY9AFAA2LPMC1-G-UNE2 equivalent, this part delivers verified low-power operation across six modes (including Deep Standby RTC), hardware watchdog with CR-oscillator backup, HDMI-CEC/remote receiver support, and IGBT-mode motor timing peripherals - all in a 100-pin LQFP package.
Technical Context
The CY9AFAA2LPMC1-G-UNE2 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. Its clock system combines five sources: 4–20 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz and 100 kHz internal CR oscillators, and a configurable Main PLL.
Peripheral integration includes a dedicated LCD controller with internal bias resistors (10 kΩ or 100 kΩ selectable), multi-function serial interfaces (up to 8 channels configurable as UART/CSIO/I²C), and motor-control-optimized timers with dead-time insertion, DC chopper waveform generation, and DTIF emergency stop interrupt capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm® Cortex®-M3 r2p1, 20 MHz max - enables deterministic real-time execution with Thumb-2 instruction set and hardware divide. |
| Flash / SRAM | 128 KB flash (0-wait-state read), 16 KB SRAM - sufficient for complex motor control algorithms and GUI logic without external memory. |
| ADC | 16-channel 12-bit SAR ADC, 1.0 µs min conversion - supports high-speed current/voltage sampling in servo drives and power supplies. |
| DAC | 2-channel 10-bit R-2R DAC - provides analog reference outputs for biasing, calibration, or feedback loop injection. |
| LCD Controller | 44 SEG × 4 COM or 40 SEG × 8 COM with internal bias resistors - drives segment-based industrial displays without external resistor networks. |
| Low-Power Modes | Six modes including Deep Standby RTC - retains RTC and 16-byte backup register while drawing <1 µA, enabling battery-backed timekeeping. |
| Operating Voltage | VCC = 1.8 V to 5.5 V (2.2–5.5 V with LCD active) - supports direct interface with 3.3 V and 5 V logic domains and legacy industrial sensors. |
Pinout & Package
This device is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are fully relocatable via port mapping registers, enabling flexible PCB layout and peripheral assignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual VCC pins (VCC1/VCC2) and multiple VSS pins ensure stable core and I/O domain decoupling; thermal pad improves heat dissipation in continuous motor control operation. |
| XTAL / EXTAL | Main clock input/output | Accepts 4–20 MHz crystal or external clock; required for PLL operation and high-precision timing in motor commutation and PWM generation. |
| OSC32 / OSC32B | 32.768 kHz sub-clock | Drives RTC and wake-up timers independently of main clock - essential for time-stamped logging and low-power scheduling. |
| LCDD0–LCDD31 | LCD segment drivers | 32 dedicated segment outputs with programmable drive strength and internal bias - eliminates need for external LCD bias circuitry. |
| AD0–AD15 | Analog input channels | 16-pin group supporting simultaneous sampling and FIFO-based scan mode - reduces CPU overhead during multi-sensor monitoring. |
| DA0 / DA1 | Digital-to-analog outputs | Two independent 10-bit voltage outputs usable for analog feedback injection or reference generation in closed-loop systems. |
Key Features
| Feature | Design Value |
|---|---|
| IGBT-mode motor timers | Integrated dead-time insertion, DC chopper waveform generation, and DTIF emergency stop interrupt - enables safe, compact inverter gate driving without external logic. |
| HDMI-CEC/Remote receiver | Dual-channel support for NEC, SIRCS, and HDMI-CEC protocols with noise filtering and automatic header transmission - simplifies remote interface design for industrial HMIs and display controllers. |
| Port relocate function | Runtime-configurable peripheral pin mapping - allows dynamic reassignment of UART, I²C, or timer outputs to alternate GPIOs, improving board layout reuse across variants. |
| Hardware watchdog with CR oscillator | Independent 100 kHz low-speed clock source keeps watchdog active in Sleep, Timer, RTC, Stop, and Deep Standby RTC modes - ensures fail-safe recovery even during deep power gating. |
| Backup register | 16-byte SRAM retained during Deep Standby Stop - stores critical state (e.g., fault counters, calibration offsets) across extended power loss without external NV memory. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz, 256 KB flash, no integrated LCD controller, single 12-bit DAC | Higher compute throughput but lacks native segment LCD drive and HDMI-CEC receiver | Select when floating-point math or higher PWM resolution is required; add external LCD driver if display needed. |
| RL78/G14 R5F104PJSP | 16-bit RL78 core, 32 MHz, 128 KB flash, 10-bit ADC, no DAC or LCD controller | Lower cost and power, but no motor-specific peripherals (dead-time, DTIF) or analog outputs | Select for simpler, cost-sensitive motion control where DAC and LCD are not required. |
Compared with STM32F303VCT6 and RL78/G14 R5F104PJSP, the CY9AFAA2LPMC1-G-UNE2 uniquely integrates LCD drive, HDMI-CEC, dual DAC, and IGBT-mode timers - reducing component count and firmware complexity in space-constrained industrial HMI and motor control designs.

FAQ
What is the maximum operating frequency and core architecture of CY9AFAA2LPMC1-G-UNE2?
The CY9AFAA2LPMC1-G-UNE2 uses an Arm® Cortex®-M3 r2p1 core with a maximum operating frequency of 20 MHz. It includes a nested vectored interrupt controller (NVIC) supporting 32 peripheral interrupts and 8 priority levels, along with a 24-bit SysTick timer for OS task scheduling. The core executes Thumb-2 instructions and supports hardware integer divide.
Does CY9AFAA2LPMC1-G-UNE2 support external memory expansion?
No, the CY9AFAA2LPMC1-G-UNE2 does not support external memory expansion via parallel bus or dedicated memory interface. It relies solely on its on-chip 128 KB flash and 16 KB SRAM. All code execution and data storage must fit within these integrated memories, which is typical for FM3-series microcontrollers targeting self-contained embedded applications.
What LCD configurations does the built-in LCDC support?
The integrated LCD controller supports two configurations: 44 segment × 4 common or 40 segment × 8 common. It includes internal bias resistors (selectable 10 kΩ or 100 kΩ), dedicated VV0–VV4 bias supply pins, frame-synchronized interrupt generation, blinking control, and inverted display mode - enabling direct drive of passive segment LCDs without external components.
How many low-power modes does CY9AFAA2LPMC1-G-UNE2 offer, and what is retained in Deep Standby RTC mode?
The device offers six low-power modes: Sleep, Timer, RTC, Stop, Deep Standby RTC, and Deep Standby Stop. In Deep Standby RTC mode, the 32.768 kHz sub-clock remains active, RTC continues counting, and the 16-byte backup register is retained - all while consuming less than 1 µA. The main PLL, flash, and most peripherals are disabled to minimize leakage current.
