Product details
Overview
CY9AF111LAPMC1-G-106NE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 64 KB on-chip Flash, 16 KB SRAM, and operation up to 40 MHz. It integrates motor control timers, dual 12-bit ADC units (9 channels total), eight multi-function serial interfaces (UART/CSIO/LIN/I²C), and supports 2.7–5.5 V supply. It targets cost-sensitive industrial motor control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the CY9AF111LAPMC1-G-106NE2 datasheet, CY9AF111LAPMC1-G-106NE2 pinout, CY9AF111LAPMC1-G-106NE2 application, or CY9AF111LAPMC1-G-106NE2 equivalent, key selection considerations include its LQI100 package compatibility, absence of External Bus Interface, support for SWJ-DP debug only (no ETM), and dual watchdog architecture (HW + SW) with CR oscillator supervision.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem separates I-code/D-code access to SRAM0 (16 KB) and system-bus-connected SRAM1 (not present in this variant), enabling deterministic instruction fetch and data handling.
The peripheral set includes eight base timers (PWM/PPG/reload/PWC modes), two QPRC units for encoder position tracking, and a CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32 - all accessible via port relocation to maximize pin flexibility in the 100-pin LQFP layout.
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 | 64 KB, 0-wait-state read - supports fast code execution without cache penalties |
| SRAM | 16 KB total (SRAM0 only) - sufficient for stack, heap, and peripheral buffers in compact firmware |
| ADC | 2 × 12-bit SAR units, 9 channels, 1.0 μs conversion @5 V - meets motor current sensing timing requirements |
| Serial Interfaces | 8-channel multi-function UART/CSIO/LIN/I²C - allows concurrent LIN bus communication and UART debugging |
| Timers | 8 base timers + 2 QPRC + 1 dual timer - provides dedicated hardware for PWM generation, encoder counting, and wake-up timing |
| Debug | SWJ-DP only (no ETM) - supports full JTAG/SWD debugging but no instruction trace capability |
| Supply Range | 2.7–5.5 V - enables direct interface with 3.3 V or 5 V logic and legacy industrial sensors |
Pinout & Package
Package: LQFP-100 (LQI100), 0.65 mm pitch, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pins 1, 97–100) | Core & I/O power supply | Accepts 2.7–5.5 V; multiple pins reduce IR drop and improve noise immunity |
| VSS (Pins 2, 95–96) | Digital ground reference | Separate analog/digital ground not implemented; shared VSS requires careful PCB layout |
| P00–P09, P20–P21, P50–P52, P60–P63, etc. | Multi-function GPIO with port relocation | Each pin supports up to 4 alternate functions (e.g., SIN4_0, INT00_2, MCSX1_1); EPFR register selects active function |
| TCK/SWCLK, TMS/SWDIO, TDI, TDO/SWO, TRSTX | Serial Wire JTAG Debug Port | Enables full SWD-based programming, breakpointing, and memory inspection without external debug adapter overhead |
| AIN0_2, BIN0_2, ZIN0_2 | Quadrature encoder inputs | Dedicated QPRC channel 0 inputs with configurable edge detection for precise position feedback |
Key Features
| Feature | Design Value |
|---|---|
| Port Relocation Engine | Permits dynamic assignment of peripheral functions (e.g., UART, LIN, ADC trigger) to any compatible GPIO, increasing board layout flexibility |
| Dual Watchdog Architecture | Independent HW watchdog (clocked by 100 kHz CR oscillator) remains active in SLEEP/TIMER modes; SW watchdog offers software-configurable timeout |
| CRC Accelerator | Hardware CRC16 (0x1021) and CRC32 (0x04C11DB7) offloads integrity checks from CPU during firmware updates or CAN/LIN message validation |
| Motor Control Timer Set | Includes dead-time insertion, DTIF emergency stop interrupt, and A/D activation compare - enables safe, synchronized PWM-driven motor drives |
| Clock Supervisor (CSV) | Detects external clock failure or frequency deviation using internal CR oscillators, triggering reset or interrupt to prevent timing-related system faults |
Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|
|
Use Scenario: Closed-loop BLDC motor control in HVAC blowers or pump systems with Hall-effect or encoder feedback. IC Role / Device Role / Timing Role: Real-time PWM generation, quadrature position capture (QPRC), and current-sense ADC sampling synchronized to motor commutation.

Use Scenario: Centralized door/window actuator control with LIN bus communication to mirror, seat, and lock modules. IC Role / Device Role / Timing Role: LIN 2.1 master node managing frame transmission, error recovery, and local sensor polling (e.g., window position, temperature). Use Value: On-chip LIN transceiver interface and hardware break field generation ensure protocol compliance without external LIN PHY. |
| Smart Power Outlet | Factory Automation I/O Hub |
|
Use Scenario: Energy-monitoring outlet with relay control, voltage/current measurement, and isolated UART for host MCU communication. IC Role / Device Role / Timing Role: Isolated UART bridge, 12-bit ADC for AC sensing, and watchdog-enforced safety monitoring of relay state. Use Value: Dual watchdog (HW + SW) and LVD2 auto-reset provide fail-safe disconnection under brownout or firmware hang conditions. |
Use Scenario: DIN-rail mounted I/O expansion unit aggregating digital inputs, analog sensor readings, and Modbus RTU over RS-485. IC Role / Device Role / Timing Role: UART-to-Modbus protocol handler with CRC32 acceleration, GPIO scanning, and periodic watchdog-triggered self-test. Use Value: Hardware CRC engine reduces Modbus frame processing time by >70% vs. software-only implementation, improving polling throughput. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072RBT6 | ARM Cortex-M0+, 48 MHz, 128 KB Flash, 16 KB SRAM, USB 2.0 FS, no QPRC or LIN | Lacks dedicated motor encoder counters and LIN protocol support; requires external transceiver for automotive comms | Select when USB connectivity is required and motor control complexity is low (e.g., simple fan speed regulation) |
| RP2040 | Dual-core ARM Cortex-M0+, 133 MHz, 264 KB SRAM, no Flash, PIO peripherals, no hardware LIN or CSV | No integrated Flash or analog peripherals; relies on external QSPI Flash and ADC; lacks clock supervision | Choose for high-throughput GPIO manipulation (e.g., LED matrix control) where deterministic analog timing is not critical |
Compared with STM32F072RBT6 and RP2040, CY9AF111LAPMC1-G-106NE2 delivers hardware-accelerated LIN 2.1, QPRC, and Clock Supervisor - making it uniquely suited for safety-aware, encoder-based industrial motion control where external component count and timing reliability are primary constraints.

FAQ
Does CY9AF111LAPMC1-G-106NE2 support External Bus Interface (EBI)?
No. This variant does not implement the External Bus Interface. The datasheet explicitly states that CY9AF111LA, F112LA, and F114LA devices omit EBI functionality. Memory expansion must be handled via SPI-connected Flash or external serial EEPROM instead of parallel NOR Flash or SRAM.
What debug capabilities does this MCU offer?
It supports Serial Wire JTAG Debug Port (SWJ-DP) only - including SWD and JTAG protocols - but does not integrate Embedded Trace Macrocell (ETM). Full flash programming, register inspection, and breakpoint debugging are supported; however, real-time instruction trace is unavailable.
Is the 12-bit ADC capable of simultaneous sampling?
No. The two 12-bit ADC units operate independently but do not support hardware-synchronized sampling across channels. Each unit provides FIFO-based scan mode (16-step) and priority conversion (4-step), but inter-unit triggering or simultaneous start is not implemented in this series.
Can the built-in LIN interface operate without an external transceiver?
No. The MCU implements only the LIN protocol controller (LIN 2.1 compliant), not the physical layer. An external LIN transceiver (e.g., TLE7259-3GE) is required to drive the bus line, handle slew rate control, and provide fault protection per ISO 17987.
