Product details
Overview
CY9AF112LAPMC1-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, 80-pin LQFP package, 40 MHz max CPU frequency, and integrated motor control peripherals including 8-channel Base Timers, 2-unit MF-Timer, and 12-channel 12-bit ADC - deployed in industrial motor drives and HVAC blower control systems.
For engineers reviewing the CY9AF112LAPMC1-GNE2 datasheet, CY9AF112LAPMC1-GNE2 pinout, CY9AF112LAPMC1-GNE2 application, or CY9AF112LAPMC1-GNE2 equivalent, key selection criteria include external bus interface support (absent in this variant), 11 external interrupt pins + NMI, 66 GPIOs, LIN 2.1 compliance, and SWJ-DP debug interface without ETM.
Technical Context
This FM3-series MCU implements a deterministic real-time architecture centered on the Arm Cortex-M3 r2p1 core, with tightly coupled memory subsystem (I-code/D-code buses for SRAM0, system bus for SRAM1) and hardware-accelerated CRC (CCITT CRC16/IEEE-802.3 CRC32) for data integrity in noisy industrial environments.
Its peripheral set is optimized for closed-loop motion control: dual QPRC units track encoder position/revolution, Base Timers support PWM/PPG/PWC modes with dead-time insertion, and MF-Timer provides A/D activation compare and waveform generation synchronized to motor commutation events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic <1 µs interrupt latency for time-critical motor fault handling. |
| Memory | 128 KB Flash (0-wait-state), 16 KB SRAM (split into SRAM0/SRAM1) - supports real-time code execution and dual-bank buffering for sensor data acquisition. |
| ADC | 12-bit SAR, 12 channels, 1.0 µs conversion @5 V - sufficient resolution and speed for current sensing and temperature monitoring in BLDC drives. |
| Timers | 8-channel Base Timer (PWM/PPG/PWC), 2-unit MF-Timer (6 output compare, 4 input capture, 3 A/D activation) - enables full 3-phase motor control with synchronized sampling and dead-time management. |
| Serial Interfaces | 8-channel multi-function serial (UART/CSIO/LIN/I2C), ch.4–ch.7 with 16×9-bit FIFO - LIN 2.1 master/slave support simplifies communication with HVAC sensors and actuators. |
| Power & Safety | 2.7–5.5 V supply, dual LVD (interrupt + reset), Clock Supervisor (CSV), HW/SW watchdog - ensures robust operation across wide industrial voltage ranges and failure detection. |
| Debug | Serial Wire JTAG Debug Port (SWJ-DP), no ETM - provides full firmware download, breakpoint, and register inspection without trace overhead. |
Pinout & Package
Package: 80-pin LQFP (LQG080, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P09 | General-purpose I/O / Trace / Serial Wire Debug | Configurable as SWDIO/TCK/TMS/TDO/TRSTX or trace clock/data - enables in-system debugging without dedicated debug header. |
| P20, P50–P51 | Quadrature Encoder Inputs (AIN0/BIN0/ZIN) | Dedicated QPRC inputs with edge-configurable detection - directly interfaces to incremental encoders for rotor position feedback. |
| P60–P63 | Serial Interface Ch.5 (SIN5/SOT5/SCK5) / External Bus Ready | Full-duplex UART/CSIO/LIN channel with hardware flow control disabled - used for host MCU communication or sensor telemetry. |
| P0A–P0D | Serial Interface Ch.4 (SIN4/SOT4/SCK4/RTS4/CTS4) | Multi-function UART with RTS/CTS support - implements hardware handshaking for reliable firmware updates over RS-232/RS-485 links. |
| VCC, VSS | Power Supply / Ground | Separate analog/digital power domains not implemented - single 2.7–5.5 V rail simplifies PCB layout but requires careful decoupling for ADC accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Port Relocate Function | Peripherals can be assigned to alternate GPIO pins via EPFR registers - resolves pin conflicts when multiple high-priority functions (e.g., QPRC + ADC) share limited I/O resources. |
| Motor Control Timers | Base Timer supports PWM with programmable dead-time insertion and DTIF emergency stop trigger - prevents shoot-through in half-bridge gate drivers during fault conditions. |
| LIN 2.1 Compliance | Integrated LIN break field (13–16 bit) and delimiter (1–4 bit) generation - eliminates need for external LIN transceivers in cost-sensitive HVAC node designs. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 calculation - offloads checksum computation from CPU during CAN/LIN message validation or Flash integrity checks. |
| Low-Power Modes | SLEEP/TIMER/STOP modes with sub-clock wake-up (32.768 kHz) - extends battery life in portable industrial tools while retaining encoder position tracking in STOP mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY9AF114LAPMC1-GNE2 | 256 KB Flash, 32 KB SRAM, 100-pin LQFP, 16-channel ADC, 8-ch external interrupt pins upgraded to 16 | Supports larger firmware (e.g., embedded Modbus TCP stack) and higher-resolution current sensing in servo drives | Select when >128 KB Flash or >12 ADC channels are required; same peripheral set and debug interface |
| STM32F303K8T6 | Arm Cortex-M4F core, 72 MHz, 64 KB Flash, 16 KB SRAM, 12-bit ADC (16 ch), advanced motor control timers (BDTR, HRTIM) | Better floating-point performance for FOC algorithms; lacks integrated LIN but offers USB and CAN | Choose for field-oriented control (FOC) with complex math; CY9AF112LAPMC1-GNE2 preferred for LIN-centric HVAC nodes |
Compared with CY9AF114LAPMC1-GNE2, this part trades Flash/SRAM capacity and ADC count for lower cost and smaller footprint; versus STM32F303K8T6, it offers native LIN 2.1 and simpler toolchain integration but lacks FPU and CAN.

FAQ
Does CY9AF112LAPMC1-GNE2 support external memory expansion?
No. This variant lacks the External Bus Interface (EBI) present in higher-pin-count FM3 devices like CY9AF114LA. It relies solely on on-chip 128 KB Flash and 16 KB SRAM. The datasheet explicitly states EBI is unsupported for CY9AF112LA series, making external NOR Flash or SRAM expansion impossible without external logic.
What debug interfaces are available on CY9AF112LAPMC1-GNE2?
It supports Serial Wire JTAG Debug Port (SWJ-DP) only - no Embedded Trace Macrocell (ETM). Debug access uses standard SWD pins (TCK, TMS, TDO, TDI, TRSTX) mapped to P00–P04, enabling full firmware download, breakpoints, and register inspection, but no instruction trace capability.
Is hardware flow control supported on UART channels?
Hardware flow control (RTS/CTS) is supported only on channel 4 (pins P0D/P0C), as confirmed in the "Features" section of the datasheet. Channels 0–3 and 5–7 do not support automatic CTS/RTS control, limiting high-speed UART reliability in noise-prone environments without software handshaking.
How many quadrature encoder interfaces does this MCU provide?
It integrates two independent Quadrature Position/Revolution Counter (QPRC) units, each supporting AIN/BIN/ZIN inputs with configurable edge detection, 16-bit position/revolution counters, and dual compare registers - sufficient for dual-motor control or redundant position sensing in safety-critical applications.
