Product details
Overview
CY9AF111MAPMC-GNE2 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, 8-channel DMA, and integrated motor control peripherals including 8-base timers, 2-QPRC units, and LIN 2.1/UART/I²C/CSIO serial interfaces. It targets cost-sensitive industrial motor drives and embedded control systems requiring real-time position sensing and multi-protocol communication.
For engineers reviewing the CY9AF111MAPMC-GNE2 datasheet, CY9AF111MAPMC-GNE2 pinout, CY9AF111MAPMC-GNE2 application, or CY9AF111MAPMC-GNE2 equivalent, key selection criteria include its LQFP-100 package, 2.7–5.5 V supply range, dual watchdog (HW/SW), CRC accelerator for data integrity, and support for external bus interface with 25-bit addressing - critical for firmware update reliability and peripheral expansion in motion control designs.
Technical Context
This MCU implements a deterministic real-time execution environment via the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels. 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 without contention.
The peripheral architecture integrates tightly coupled timing resources: Base Timers support PWM/PPG/reload modes; Multi-function Timers provide input capture, output compare, and A/D activation triggers; QPRC units accept quadrature A/B/Z encoder inputs with configurable edge detection and dual 16-bit counters for position and revolution tracking - essential for closed-loop servo and BLDC motor control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic interrupt latency & real-time task scheduling |
| Flash Memory | 64 KB, 0-wait-state read - supports fast code execution and in-field firmware updates |
| SRAM | 16 KB total (8 KB SRAM0 + 8 KB SRAM1) - separates instruction/data paths to avoid bus contention |

| VCC/VSS | Power supply terminals | Multiple VCC (pins 1, 75, 97, 99) and VSS (pins 2, 74, 96, 100) - reduce power delivery impedance and improve noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Port Relocate Function | Permits dynamic assignment of peripheral functions (e.g., UART, LIN, QPRC) to alternate GPIO pins - simplifies PCB layout and avoids signal congestion |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 calculation - offloads integrity checks from CPU during firmware OTA updates or CAN/LIN message validation |
| Clock Supervisor (CSV) | Detects external clock stop/frequency anomaly using internal CR oscillators - triggers reset/interrupt to prevent runaway operation in safety-critical motor control |
| Low-Voltage Detector (LVD) | Two-stage monitoring (LVD1 interrupt, LVD2 reset) at user-configurable thresholds - ensures graceful shutdown before brownout-induced register corruption |
| External Bus Interface | 8 chip selects, 25-bit address, 8-/16-bit data - enables direct connection to external NOR Flash or SRAM for boot code storage or data logging buffers |

FAQ
What debug interface does CY9AF111MAPMC-GNE2 support?
CY9AF111MAPMC-GNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) only - it does not include Embedded Trace Macrocell (ETM). Debugging uses standard SWD protocol via TCK, TMS, TDI, TDO, and SWDIO pins, enabling full breakpoint, watchpoint, and memory inspection capabilities without requiring additional trace pins.
Does this MCU support external memory expansion?
Yes - CY9AF111MAPMC-GNE2 includes an External Bus Interface with up to 8 chip selects, 25-bit address bus, and 8-/16-bit data bus, supporting SRAM and NOR Flash devices. This allows direct connection to external program memory or data buffers, unlike many Cortex-M3 devices that rely solely on internal Flash.
How many LIN channels can operate simultaneously?
CY9AF111MAPMC-GNE2 supports up to 4 LIN channels (ch.0–ch.3) concurrently, each configurable independently as master or slave. All LIN channels implement LIN 2.1 protocol features including programmable break field length (13–16 bits), automatic sync field handling, and error detection for parity, framing, and overrun conditions.
Is the QPRC unit capable of handling index pulse (Z-phase) inputs?
Yes - the Quadrature Position/Revolution Counter (QPRC) includes dedicated ZIN input pins with configurable edge detection. The Z-input resets the 16-bit position counter and increments the 16-bit revolution counter, enabling absolute position tracking across multiple mechanical rotations - critical for robotic joint control and CNC axis positioning.
