Product details
Overview
CY9AF114LPMC-GE1 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 Timer, 2-unit Multi-function Timer, 2-channel QPRC, and LIN 2.1/UART/I²C/CSIO serial interfaces. It operates from 2.7 V to 5.5 V at up to 40 MHz and targets industrial motor drives and embedded control systems requiring deterministic timing and real-time ADC-triggered waveform generation.
For engineers reviewing the CY9AF114LPMC-GE1 datasheet, CY9AF114LPMC-GE1 pinout, CY9AF114LPMC-GE1 application, or CY9AF114LPMC-GE1 equivalent, key selection criteria include its 16-channel 12-bit ADC with 1.0 μs conversion time, dual watchdog (HW + SW), CRC accelerator supporting CCITT CRC16 and IEEE-802.3 CRC32, and support for external bus interface with 25-bit addressing and 8 chip selects - critical for systems integrating NOR Flash or SRAM expansion.
Technical Context
The CY9AF114LPMC-GE1 implements a tightly coupled 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 connects to I-code/D-code buses for instruction/data caching, while SRAM1 connects to the system bus for DMA-accessible buffers.
Peripherals are organized for deterministic motor control: Base Timers provide PWM/PPG/reload modes; Multi-function Timers integrate input capture, output compare, A/D activation compare, and waveform generation; QPRC units accept quadrature encoder inputs (AIN/BIN/ZIN) with configurable edge detection and independent 16-bit position/revolution counters; and the LIN module supports master/slave operation with programmable break field (13–16 bit) and delimiter (1–4 bit).

FAQ
What debug interface does CY9AF114LPMC-GE1 support?
The CY9AF114LPMC-GE1 supports Serial Wire JTAG Debug Port (SWJ-DP) with TCK, TMS, TDI, TDO, TRSTX, and SWO pins. It does not include Embedded Trace Macrocell (ETM); trace capability is limited to SWO-based instruction and data streaming. Debug access requires standard ARM-compliant tools such as Segger J-Link or ST-LINK v2-1 with SWD protocol support.
Does CY9AF114LPMC-GE1 support hardware flow control on UART?
No. According to the official datasheet (Rev. *H, page 2), hardware flow control (CTS/RTS) is explicitly unsupported on CY9AF114L series devices, including CY9AF114LPMC-GE1. UART channels 4–7 support FIFO but lack RTS/CTS signal routing; software-controlled XON/XOFF or application-level handshaking must be used instead.
What is the maximum operating temperature range for CY9AF114LPMC-GE1?
The CY9AF114LPMC-GE1 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 "Recommended Operating Conditions" of the datasheet (Document Number 002-04672 Rev. *H), where VCC = 2.7–5.5 V operation is specified across this full range without derating.
Can CY9AF114LPMC-GE1 directly drive 5 V logic peripherals?
Only specific pins are 5V tolerant: the datasheet states "Some ports are 5V tolerant I/O (CY9AF115MA/NA, CY9AF116MA/NA only)" - meaning CY9AF114LPMC-GE1 does not support 5V-tolerant I/O. All GPIOs operate at VCC level (2.7–5.5 V), and applying 5 V to pins when VCC < 5 V may cause damage. Level-shifting is required for interfacing with 5 V peripherals.
