Product details
Overview
CY9AF111LPMC1-GE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 64 KB on-chip Flash, 16 KB SRAM, 40 MHz max CPU frequency, 51 GPIO pins, and integrated motor control peripherals including 8-channel Base Timers, 2-unit A/D converter (9 channels), and LIN/UART/I²C/CSIO serial interfaces. It targets cost-sensitive industrial motor drives and embedded control systems requiring real-time timing, analog sensing, and multi-protocol communication.
For engineers reviewing the CY9AF111LPMC1-GE1 datasheet, CY9AF111LPMC1-GE1 pinout, CY9AF111LPMC1-GE1 application, or CY9AF111LPMC1-GE1 equivalent, key selection criteria include its LQFP-64 package, 2.7–5.5 V supply range, hardware watchdog + software watchdog, dual-stage LVD, and absence of External Bus Interface - critical for compact, low-power motor control designs without external memory expansion.
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 includes two independent SRAM banks (SRAM0/SRAM1) mapped to I-code/D-code and system buses respectively, enabling concurrent instruction fetch and data access.
The peripheral set is optimized for deterministic motor control: Base Timers support PWM, PPG, reload, and PWC modes; QPRC units decode quadrature encoder signals; and MF-Timer provides input capture, output compare, and A/D activation triggers. LIN 2.1 compliance and hardware flow control omission (per datasheet footnote) define its serial interface constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - delivers deterministic real-time execution with Thumb-2 instruction set and low-latency interrupt handling. |
| Flash Memory | 64 KB, 0-wait-state read - enables fast code execution without cache penalties in resource-constrained applications. |
| SRAM | 16 KB total (SRAM0: 8 KB, SRAM1: 8 KB) - split architecture supports parallel instruction/data access for time-critical ISR routines. |
| A/D Converter | 2 × 12-bit SAR units, 9 channels, 1.0 μs conversion @5 V - sufficient for simultaneous current/voltage feedback sampling in 3-phase motor control. |
| Timers | 8-channel Base Timer + 1-unit MF-Timer (3× free-run, 4× input capture, 6× output compare) - enables full-featured PWM generation, dead-time insertion, and encoder position tracking. |
| Serial Interfaces | 8-channel Multi-function Serial (UART/CSIO/LIN/I²C), ch.4–ch.7 with 16×9-bit FIFO - supports LIN master/slave for automotive body control and UART debug without external buffers. |
| Power Supply | 2.7–5.5 V operation - compatible with wide-range industrial power rails and eliminates need for external LDO in 3.3 V or 5 V systems. |
Pinout & Package
LQFP-64 package (0.5 mm pitch, 10 mm × 10 mm body), RoHS-compliant, with exposed thermal pad. Pin count and I/O allocation match CY9AF111LA series specification: 51 general-purpose I/O pins, 8 external interrupt inputs + NMI, and dedicated SWJ-DP debug interface (TCK/TMS/TDI/TDO/TRSTX).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual VCC pins (pins 1, 64) and dual VSS pins (pins 2, 63) ensure stable core and I/O rail decoupling in noise-sensitive motor environments. |
| P00–P0F, P20, P50–P51, P60–P63 | GPIO / Peripheral multiplexing | 51 configurable I/Os with port relocate function - allows flexible PCB layout by assigning UART, LIN, or timer outputs to alternate pins without redesign. |
| TCK, TMS, TDI, TDO, TRSTX | SWJ-DP debug interface | Standard 5-pin JTAG/SWD connection - enables in-circuit programming and real-time debugging without additional protocol converters. |
| INT00_0–INT03_0, INT15_1 | External interrupt inputs | 8 dedicated interrupt pins + 1 NMI - supports fast response to encoder zero-crossing, fault signals, or emergency stop events. |
| SIN4_0/SOT4_0/SCK4_0, SIN5_0/SOT5_0/SCK5_0 | LIN/UART/CSIO channel 4 & 5 | Dedicated LIN transceiver pins (SIN/SOT) with built-in break field generation - meets ISO 17987-2 physical layer requirements for automotive sub-networks. |
Key Features
| Feature | Design Value |
|---|---|
| Motor Control Timer Set | 8-channel Base Timer + 1-unit MF-Timer with A/D activation compare - enables synchronized PWM updates and current-sampling triggers within single timer cycle. |
| Quadrature Encoder Interface | 2× QPRC units with 16-bit position/revolution counters and configurable AIN/BIN/ZIN edge detection - directly interfaces standard incremental encoders without external logic. |
| Low-Power Management | SLEEP/TIMER/STOP modes with Watch Counter wake-up (up to 64 s @32.768 kHz) and dual-stage LVD reset/interrupt - extends battery life in portable motor tools and reduces system-level power sequencing complexity. |
| Clock Supervision | Clock Supervisor (CSV) monitors external crystal failure/frequency drift using internal CR oscillators - prevents runaway operation during clock source degradation without external watchdog IC. |
| CRC Acceleration | Hardware CCITT CRC16 and IEEE-802.3 CRC32 engines - offloads integrity checking from CPU during firmware OTA updates or LIN message validation, reducing latency by >90% vs software CRC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072RBT6 | 48 MHz Cortex-M0+, 128 KB Flash, 16 KB SRAM, no QPRC, only 1× 12-bit ADC (16 ch) | Lacks dedicated quadrature encoder counters and motor-specific timers; requires software-based PWM synchronization | Select when cost is primary constraint and encoder resolution ≤10-bit suffices; avoid for high-precision servo positioning. |
| RL78/F13 | 32 MHz RL78 core, 128 KB Flash, 12 KB RAM, 12-bit ADC (12 ch), no LIN, only UART/I²C | No native LIN support; uses software-based LIN stack consuming ~8 KB Flash and increasing CPU load | Choose for non-automotive applications where LIN is unnecessary and ultra-low power (<0.5 μA STOP mode) is mandatory. |
Compared with STM32F072RBT6 and RL78/F13, CY9AF111LPMC1-GE1 provides superior motor control integration via hardware QPRC, dual ADC units, and LIN 2.1 compliance - reducing firmware complexity by 40% and enabling sub-μs timing determinism required for field-oriented control.

FAQ
Does CY9AF111LPMC1-GE1 support external memory expansion?
No. Unlike higher-pin-count FM3 variants (e.g., CY9AF114LA), CY9AF111LPMC1-GE1 omits the External Bus Interface. Its 64 KB Flash and 16 KB SRAM are intended for self-contained applications; external NOR Flash or SRAM must be interfaced via GPIO bit-banging or SPI peripherals if required.
What debug interfaces does CY9AF111LPMC1-GE1 provide?
CY9AF111LPMC1-GE1 supports Serial Wire JTAG Debug Port (SWJ-DP) only - no Embedded Trace Macrocell (ETM). The 5-pin interface (TCK/TMS/TDI/TDO/TRSTX) enables full flash programming, breakpoint setting, and real-time variable inspection using standard ARM-compatible debug probes like Segger J-Link or ST-Link v2.
Is hardware flow control supported on UART channels?
No. Per datasheet footnote on page 2, hardware flow control (CTS/RTS) is explicitly unsupported on CY9AF111LA-series devices including CY9AF111LPMC1-GE1. UART channels 0–3 and 4–7 operate in full-duplex mode with software-controlled handshaking only.
What is the maximum operating temperature range for CY9AF111LPMC1-GE1?
CY9AF111LPMC1-GE1 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 "Recommended Operating Conditions" of datasheet 002-04672 Rev. *H, making it suitable for enclosed motor drive enclosures and under-hood automotive modules.
