Product details
Overview
CY9AF112LPMC-GE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 128 KB on-chip Flash, 16 KB SRAM, and integrated motor control peripherals including 8-channel Base Timers, 2-unit Multi-function Timers, and 12-channel 12-bit ADC. It operates up to 40 MHz across 2.7–5.5 V and targets industrial motor drives and embedded control systems requiring real-time PWM, quadrature encoding, and LIN/UART/I²C communication.
For engineers reviewing the CY9AF112LPMC-GE1 datasheet, CY9AF112LPMC-GE1 pinout, CY9AF112LPMC-GE1 application, or CY9AF112LPMC-GE1 equivalent, key selection criteria include its LQI100 package, dual watchdog (HW/SW), CRC accelerator support for CCITT CRC16/IEEE-802.3 CRC32, External Bus Interface (25-bit address, 8-/16-bit data), and QPRC for position sensing in BLDC/PMSM motor control.
Technical Context
This MCU implements a deterministic real-time control architecture centered on the Arm Cortex-M3 r2p1 core, with dedicated hardware accelerators for motor timing (PPG, PWC, DTIF), A/D conversion triggering, and encoder position tracking via two independent QPRC units. Its memory subsystem separates instruction (SRAM0) and system (SRAM1) buses to reduce contention during DMA transfers.
The peripheral set is optimized for closed-loop motion control: Base Timers provide 16-/32-bit reload/PWM/PPG modes; Multi-function Timers deliver input capture, output compare, and waveform generation; and the 12-channel ADC supports priority/scanning conversion with FIFO buffering for sensor data acquisition at ≤1.0 µs per sample @5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic interrupt latency & RTOS compatibility |
| Flash Memory | 128 KB, 0-wait-state read - supports fast code execution without cache penalties |
| SRAM | 16 KB total (SRAM0 + SRAM1), split-bus architecture - reduces CPU/DMA bus contention |
| ADC | 12-bit, 12 channels, 1.0 µs conversion @5 V - sufficient resolution/speed for current/voltage sensing in motor control |
| Timers | 8-channel Base Timer + 2-unit MF-Timer + 2×QPRC - provides full PWM generation, dead-time insertion, and encoder position feedback |
| Communication | 8-channel multi-serial interface (UART/CSIO/LIN/I²C), 4 with 16×9-bit FIFO - enables concurrent protocol handling with minimal CPU overhead |
| Power Range | 2.7–5.5 V operation - compatible with industrial 3.3 V and legacy 5 V supply rails |

Key Features
| Feature | Design Value |
|---|---|
| Hardware Watchdog (HW-WDT) | Clocked by 100 kHz built-in CR oscillator - remains active in all low-power modes except STOP, ensuring fail-safe reset during sleep |
| Quadrature Position Counter (QPRC) | Two independent 16-bit position + 16-bit revolution counters - directly interfaces incremental encoders for precise rotor position in BLDC/PMSM drives |
| CRC Accelerator | Supports CCITT CRC16 (0x1021) and IEEE-802.3 CRC32 (0x04C11DB7) - offloads integrity checks from CPU for CAN/LIN frame validation or flash data verification |
| External Bus Interface (EBI) | 25-bit address, 8-/16-bit data, 8 chip selects - enables direct connection to external NOR Flash or SRAM for code expansion or data logging |
| Port Relocate Function | EPFR-based peripheral pin mapping - allows flexible PCB layout by assigning UART, timer, or ADC functions to alternate GPIO pins |

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, 48 KB RAM, no EBI, integrated op-amps/comparators | Lacks External Bus Interface and QPRC; stronger analog front-end but weaker encoder interface | Select when analog signal conditioning dominates over external memory or high-resolution position feedback |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4, 48 MHz, 256 KB Flash, 32 KB RAM, no EBI, 2×QEI modules (not QPRC) | QEI supports index pulse but lacks separate revolution counter; no hardware DTIF interrupt | Select for general-purpose industrial control where encoder resolution < 16-bit suffices and external memory not required |
Compared with STM32F303VCT6 and RA4M1, CY9AF112LPMC-GE1 uniquely combines EBI for external code/data storage, dual QPRC with independent position/revolution counters, and DTIF for hardware-triggered motor shutdown-making it optimal for cost-sensitive, high-reliability motor drives needing encoder-based commutation and firmware extensibility.

FAQ
What debug interfaces does CY9AF112LPMC-GE1 support?
CY9AF112LPMC-GE1 supports Serial Wire JTAG Debug Port (SWJ-DP) only-Embedded Trace Macrocell (ETM) is not implemented in this variant. Debug access uses TCK, TMS, TDI, TDO, and TRSTX pins; SWO provides asynchronous trace output. No JTAG-only mode is available-the interface defaults to SWD when TMS is held high during reset.
Does CY9AF112LPMC-GE1 support hardware flow control on UART?
No-hardware flow control (CTS/RTS) is explicitly excluded from CY9AF112L and CY9AF112LA variants per datasheet footnote on page 2. Only software XON/XOFF flow control is supported on UART channels. This omission reduces pin count and simplifies PCB routing for applications where burst-mode transmission suffices.
What is the maximum operating frequency of the main PLL?
The main PLL supports up to 40 MHz output frequency, derived from internal 4 MHz CR oscillator or external crystal (4–48 MHz). PLL multiplication ratio is programmable, but final CPU clock is capped at 40 MHz regardless of input source. This limit ensures consistent timing margins for all on-chip peripherals including ADC, timers, and serial interfaces.
How many 12-bit ADC units are integrated in CY9AF112LPMC-GE1?
CY9AF112LPMC-GE1 integrates two independent 12-bit successive approximation ADC units, supporting up to 12 total input channels. Each unit has dedicated FIFO (16-step for scanning, 4-step for priority mode) and supports simultaneous sampling triggers from Base Timer or MF-Timer compare events-enabling synchronized current/voltage acquisition in motor control loops.
