Infineon Technologies CY9AF114NPMC-GE1

Overview

CY9AF114NPMC-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, and 16-channel 12-bit ADC. It operates at up to 40 MHz across 2.7–5.5 V and targets industrial motor drives.

For engineers reviewing the CY9AF114NPMC-GE1 datasheet, CY9AF114NPMC-GE1 pinout, CY9AF114NPMC-GE1 application, or CY9AF114NPMC-GE1 equivalent, key selection criteria include external bus interface support (25-bit address, 8-/16-bit data, 8 chip selects), dual watchdog timers (HW + SW), CRC accelerator (CCITT CRC16/IEEE-802.3 CRC32), and QPRC for encoder position sensing.

Technical Context

This MCU 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 on I-code/D-code buses, SRAM1 on system bus-enabling concurrent CPU and DMA access.

The peripheral set includes 8-channel DMA controller with 32-bit addressing, 8-channel multi-function serial interface (UART/CSIO/LIN/I2C) with configurable FIFO depth per channel, and clock supervision via CSV monitoring external oscillator failure or frequency anomaly. Low-power operation supports SLEEP, TIMER, and STOP modes with wake-up via Watch Counter or external interrupt.

FAQ

What is the maximum operating frequency and voltage range for CY9AF114NPMC-GE1?

The CY9AF114NPMC-GE1 operates at up to 40 MHz across a supply voltage range of 2.7 V to 5.5 V. Its internal PLL supports clock multiplication from external crystal or built-in CR oscillators, and all DC/AC characteristics-including Flash read timing and ADC conversion-are guaranteed across this full voltage and temperature range per datasheet Rev. *H.

Does CY9AF114NPMC-GE1 support hardware LIN protocol implementation?

Yes, CY9AF114NPMC-GE1 integrates dedicated LIN hardware supporting LIN 2.1 specification, including programmable break field (13–16 bits), break delimiter (1–4 bits), automatic checksum calculation, and error detection (parity, framing, overrun). No external transceiver is needed for basic LIN node operation.

How many ADC channels and what resolution does CY9AF114NPMC-GE1 provide?

CY9AF114NPMC-GE1 includes three 12-bit successive approximation ADC units totaling 16 input channels. Conversion time is 1.0 μs at 5 V, with configurable priority levels, scanning mode, and built-in FIFO (16-step for scan, 4-step for priority) to reduce CPU polling overhead.

Is external memory expansion supported, and what interface options are available?

Yes, CY9AF114NPMC-GE1 supports external memory expansion via its External Bus Interface with up to 25-bit address lines, 8-/16-bit data width, 8 chip selects, and support for SRAM and NOR Flash devices. It also supports address/data multiplexing and external RDY handshake for timing flexibility.
