Product details
Overview
CY9AF114LAQN-G-AVE2 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 at up to 40 MHz across 2.7–5.5 V and targets industrial motor drives and embedded control systems requiring LIN, UART, I²C, and CSIO interfaces.
For engineers reviewing the CY9AF114LAQN-G-AVE2 datasheet, CY9AF114LAQN-G-AVE2 pinout, CY9AF114LAQN-G-AVE2 application, or CY9AF114LAQN-G-AVE2 equivalent, key selection criteria include its 100-pin LQI100 package mapping, dual watchdog (HW + SW), CRC accelerator supporting CCITT CRC16/IEEE-802.3 CRC32, external bus interface (25-bit address, 8-/16-bit data, 8 chip selects), and QPRC support for encoder-based 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 connected to I-code/D-code buses for instruction/data caching, SRAM1 on the system bus for DMA-accessible buffers.
The peripheral set is optimized for real-time motor control: Base Timers support PWM/PPG/reload/PWC modes; Multi-function Timers provide input capture, output compare, A/D activation, and waveform generation; QPRC units track quadrature encoder position and revolution count with configurable AIN/BIN/ZIN edge detection and dual 16-bit compare registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - enables deterministic interrupt latency and efficient C/C++ code execution for real-time control loops. |
| Flash Memory | 256 KB, zero-wait-state read - supports fast firmware execution without cache penalties in cost-sensitive applications. |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1) - separates CPU instruction/data access from DMA-peripheral buffering to avoid bus contention. |
| ADC | 16-channel 12-bit SAR, 1.0 μs conversion @5 V - delivers high-resolution current/voltage sampling for closed-loop motor control. |
| Timers | 8-channel Base Timer + 2-unit MF-Timer (each with 3× free-run, 4× input capture, 6× output compare) - provides flexible PWM generation, dead-time insertion, and encoder synchronization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit Arm Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VCT6 | 72 MHz Cortex-M3, 256 KB Flash, 48 KB SRAM, no external bus interface, no QPRC, only 10-channel 12-bit ADC | Lacks encoder interface and external memory support - unsuitable for high-channel-count motor control or legacy NOR Flash boot designs | Select when higher CPU clock speed is prioritized over motor-specific peripherals and external memory expansion. |
| RA4M1 (R7FA4M1AB3CFM) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, no external bus interface, no QPRC, 14-channel 12-bit ADC | Includes FPU but omits QPRC and external bus - better for floating-point math than position-critical motion control | Select when algorithmic complexity (e.g., PID tuning, filtering) outweighs encoder resolution requirements and memory scalability needs. |

FAQ
What is the maximum operating frequency and voltage range for CY9AF114LAQN-G-AVE2?
The CY9AF114LAQN-G-AVE2 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-have been characterized across this full voltage and temperature range per Document 002-04672 Rev. *H Section 12.
