Product details
Overview
CY9AF114LAPMC1-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 256 KB on-chip Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), 100-pin LQFP package, and integrated motor control peripherals including 8-channel Base Timers, 2-unit Multi-function Timers, and 16-channel 12-bit ADC. It operates from 2.7 V to 5.5 V at up to 40 MHz and targets industrial motor drives and embedded control systems.
For engineers reviewing the CY9AF114LAPMC1-GNE2 datasheet, CY9AF114LAPMC1-GNE2 pinout, CY9AF114LAPMC1-GNE2 application, or CY9AF114LAPMC1-GNE2 equivalent, key selection criteria include its 100-pin LQFP footprint, dual watchdog timers (HW + SW), external bus interface supporting 25-bit addressing and 8 chip selects, and LIN 2.1/UART/I²C/CSIO serial capability across 8 configurable channels.
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 features zero-wait-state Flash execution and dual-bus SRAM architecture-SRAM0 connected to I-code/D-code buses for core access, SRAM1 on the system bus for DMA/peripheral use.
The peripheral set is optimized for real-time motor control: QPRC units support quadrature encoder position sensing; Base Timers provide PWM/PPG/reload modes; Multi-function Timers integrate input capture, output compare, A/D activation triggers, and waveform generation; and the dual watchdog system uses independent clocks (CR oscillator for hardware WDT, programmable clock for software WDT) to ensure fail-safe operation in safety-critical environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic real-time interrupt response and efficient C/C++ code execution for embedded control. |
| Flash Memory | 256 KB, 0 wait-state - supports fast boot and real-time firmware updates without performance penalty. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1) - separates instruction/data access from DMA-peripheral traffic to prevent bus contention. |
| ADC | 16-channel, 12-bit SAR, 1.0 μs conversion @5 V - provides high-resolution analog sensing for motor current/voltage feedback loops. |
| Timers | 8-channel Base Timer + 2-unit MF-Timer (each with 3 free-run, 4 capture, 6 compare, 3 A/D trigger channels) - delivers comprehensive timing resources for multi-axis motor commutation and protection logic. |
| Serial Interfaces | 8-channel UART/CSIO/LIN/I²C with FIFO on ch.4–ch.7 - enables concurrent communication with motor drivers, sensors, and host controllers without CPU overhead. |
| External Bus | 25-bit address, 8-/16-bit data, 8 chip selects - allows direct connection to external NOR Flash or SRAM for extended program storage or data buffering. |
| Power Supply | 2.7 V to 5.5 V operation - ensures compatibility with industrial 3.3 V and 5 V supply rails and robustness against voltage transients. |
Pinout & Package
Package: 100-pin LQFP (LQI100), 0.65 mm pitch, body size 14 × 14 mm, exposed pad not specified. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (pins 1, 97, 98) | Core & I/O power supply | Supplies 2.7–5.5 V to internal logic and GPIO; multiple pins reduce IR drop and improve noise immunity. |
| VSS (pins 2, 99, 100) | Digital ground reference | Provides low-impedance return path for core, peripherals, and I/O; dedicated pins minimize ground bounce. |
| P00–P09, P20, P50–P63, etc. | Multi-function GPIO | Configurable as UART/LIN/I²C/SPI/ADC inputs or PWM outputs via port relocate function (EPFR); up to 83 usable I/Os in this package. |
| TCK/SWCLK, TMS/SWDIO, TDO/SWO, TRSTX | SWJ-DP debug interface | Enables full JTAG/SWD debugging and programming without requiring additional debug headers or pins. |
| AIN0_2, BIN0_2, ZIN_2 (P50, P51, P52) | QPRC encoder inputs | Dedicated quadrature A/B/Z inputs with configurable edge detection for precise position/speed measurement of rotary encoders. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Watchdog Timer | Driven by built-in 100 kHz CR oscillator - remains active in all low-power modes except STOP, enabling reliable system recovery during sleep. |
| CRC Accelerator | Supports CCITT CRC16 and IEEE-802.3 CRC32 - offloads integrity checking from CPU for firmware OTA updates and communication frame validation. |
| Clock Supervisor (CSV) | Monitors external main clock for stop/frequency anomaly - asserts reset or interrupt to prevent erratic operation due to crystal failure or drift. |
| Low-Voltage Detector (LVD) | Two-stage monitoring (LVD1 interrupt, LVD2 reset) - protects against brown-out conditions while allowing graceful shutdown or fault logging before reset. |
| Port Relocate Function | Permits dynamic assignment of peripheral functions (e.g., UART0, LIN1) to alternate GPIO pins - increases PCB layout flexibility and reduces routing congestion. |

FAQ
What is the maximum operating frequency and supported voltage range for CY9AF114LAPMC1-GNE2?
The CY9AF114LAPMC1-GNE2 operates at up to 40 MHz and supports a supply voltage range of 2.7 V to 5.5 V. This wide voltage range allows direct compatibility with both 3.3 V and 5 V industrial and automotive power domains without level-shifting circuitry. The 40 MHz limit is tied to the Arm Cortex-M3 core's timing closure and flash access characteristics under specified VCC and temperature conditions.
Does CY9AF114LAPMC1-GNE2 support hardware flow control on its UART interfaces?
No, CY9AF114LAPMC1-GNE2 does not support hardware flow control (CTS/RTS) on any UART channel. According to the official datasheet (Rev. *H, page 2), hardware flow control is explicitly excluded for CY9AF111LA, F112LA, F114LA, F112L, and F114L variants. Only software-based flow control (XON/XOFF) or application-layer handshaking can be implemented.
How many A/D converter units and channels does CY9AF114LAPMC1-GNE2 integrate?
CY9AF114LAPMC1-GNE2 integrates three 12-bit successive approximation A/D converter units, totaling 16 input channels. Each unit supports scanning mode with 16-step FIFO and priority conversion with 4-step FIFO. Conversion time is 1.0 μs at 5 V, and the ADCs are synchronized with timer-triggered sampling for precise motor current acquisition.
Is the External Bus Interface (EBI) available on CY9AF114LAPMC1-GNE2, and what memory types does it support?
Yes, CY9AF114LAPMC1-GNE2 includes a fully functional External Bus Interface supporting SRAM and NOR Flash devices. It provides up to 8 chip selects, 25-bit addressing (up to 256 MB space), and 8-/16-bit data width with address/data multiplexing and external RDY signal support - enabling direct attachment of external program memory or data buffers without glue logic.
