Product details
Overview
CY9AF115NAPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 384 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, 3-unit 12-bit ADC (16 channels total), and QPRC for encoder position sensing. It operates at up to 40 MHz across 2.7–5.5 V and targets industrial motor drives and embedded control systems.
For engineers reviewing the CY9AF115NAPMC-GNE2 datasheet, CY9AF115NAPMC-GNE2 pinout, CY9AF115NAPMC-GNE2 application, or CY9AF115NAPMC-GNE2 equivalent, key selection criteria include its 100-pin LQFP footprint, dual watchdog (HW + SW), external bus interface supporting 8 chip selects and 25-bit addressing, CRC accelerator for IEEE-802.3/CRC16, and SWJ-DP debug interface without ETM.
Technical Context
This FM3-series 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-to enable concurrent CPU and DMA access.
The peripheral set includes eight configurable serial interfaces (UART/CSIO/LIN/I²C), with channels 4–7 featuring 16×9-bit FIFOs; a dedicated LIN module compliant with Rev. 2.1 supporting break field (13–16 bit) and delimiter (1–4 bit) programmability; and a hardware CRC accelerator supporting CCITT CRC16 (0x1021) and IEEE-802.3 CRC32 (0x04C11DB7).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 40 MHz - enables deterministic real-time control with low-latency interrupt handling |
| Flash Memory | 384 KB, zero-wait-state read - supports fast code execution and firmware updates without performance penalty |
| SRAM | 32 KB total (16 KB SRAM0 + 16 KB SRAM1) - dual-bus allocation allows simultaneous CPU instruction fetch and DMA data transfer |
| ADC | 12-bit SAR, 16 channels, 1.0 μs conversion @5 V - meets timing requirements for high-speed current/voltage sampling in motor control loops |
| Timers | 8-channel Base Timer (PWM/PPG/reload/PWC), 2-unit Multi-function Timer (6 output compare + 4 input capture) - provides full waveform generation and feedback capture for 3-phase inverter control |
| Communication | 8 serial channels (UART/CSIO/LIN/I²C), LIN v2.1 compliant - enables robust automotive-grade communication with configurable break/delimiter timing |
| Debug | Serial Wire JTAG Debug Port (SWJ-DP), no ETM - supports standard IDE-based debugging and traceless firmware validation |
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 | Accepts 2.7–5.5 V; multiple pins reduce IR drop and improve noise immunity in high-current switching applications |
| VSS (pins 2, 96, 99) | Digital ground reference | Separate analog/digital ground not implemented; shared VSS requires careful PCB layout for mixed-signal stability |
| P00–P09, P60–P63, etc. | Multi-function GPIO | Supports port relocation via EPFR register; enables flexible peripheral mapping without board redesign |
| P0A–P0F, P20, P50–P51 | Peripheral function pins | Include SIN4_0/SOT4_0 (UART ch.4), AIN0_2/BIN0_2 (QPRC inputs), INT00_0/INT01_0 (external interrupts) - direct encoder and serial interface connectivity |
| TCK/SWCLK, TMS/SWDIO, TDO/SWO, TRSTX | JTAG/SWD debug interface | 4-pin SWJ-DP implementation - sufficient for flash programming and runtime debugging without trace bandwidth overhead |
Key Features
| Feature | Design Value |
|---|---|
| External Bus Interface | 8 chip selects, 25-bit address, 8-/16-bit data width - enables direct connection to external NOR Flash or SRAM for code offloading or data logging |
| Quadrature Position Counter | 2 units, 16-bit position + 16-bit revolution counters with AIN/BIN/ZIN edge configuration - eliminates need for external encoder IC in BLDC/PMSM position feedback |
| Clock Supervisor (CSV) | Detects external clock stop/frequency anomaly using internal CR oscillators - ensures fail-safe operation in safety-critical motor control without external monitoring circuitry |
| Low-Voltage Detector | Two-stage (LVD1 interrupt, LVD2 reset) with user-configurable thresholds - provides graceful shutdown or fault recovery before brownout-induced corruption |
| DMA Controller | 8 channels, independent bus, 32-bit addressing - enables zero-CPU-overhead transfers between ADC buffers, UART FIFOs, and SRAM for deterministic sensor-to-actuator latency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | 48 MHz Cortex-M4F, 256 KB Flash, 48 KB SRAM, no external bus interface, 16-channel 12-bit ADC with hardware oversampling | Lacks QPRC and external memory interface; relies on internal RAM for control buffers | Prefer when floating-point math or higher ADC resolution via oversampling is required, and external memory is unnecessary |

FAQ
What is the maximum operating frequency and voltage range for CY9AF115NAPMC-GNE2?
The CY9AF115NAPMC-GNE2 operates at up to 40 MHz across a supply voltage range of 2.7 V to 5.5 V. This wide voltage range supports direct integration with 3.3 V and 5 V system rails without level-shifting, and the 40 MHz clock enables sub-microsecond interrupt response times critical for real-time motor control loops.
Does CY9AF115NAPMC-GNE2 support hardware debug and trace capabilities?
It supports Serial Wire JTAG Debug Port (SWJ-DP) for full firmware download, breakpoint setting, and register inspection. However, it does not include Embedded Trace Macrocell (ETM); trace functionality is limited to SWO (Serial Wire Output) for printf-style instrumentation, not full instruction trace.
How many ADC channels and what resolution does the device provide?
The device integrates three 12-bit successive approximation ADC units totaling 16 input channels. Conversion time is 1.0 μs at 5 V supply, and it supports both scanning mode (16-step FIFO) and priority mode (4-step FIFO), enabling synchronized sampling of multiple motor phase currents and DC-link voltage.
Is external memory interfacing supported, and what are the interface limits?
Yes, the External Bus Interface supports up to 8 chip selects, 25-bit addressing (256 MB max), and 8-/16-bit data width. It connects to SRAM and NOR Flash devices with address/data multiplexing and external RDY signal support-enabling firmware updates and data logging without relying solely on internal Flash endurance limits.
