Infineon Technologies CY9AF315NAPMC-GNE2

Overview

CY9AF315NAPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including QPRC, multi-function timers, and PWM-capable base timers. It operates up to 40 MHz, supports 2.7–5.5 V supply, and targets embedded motor control and industrial automation systems requiring real-time I/O, LIN/UART/I²C/CSIO serial interfaces, and deterministic interrupt handling.

For engineers reviewing the CY9AF315NAPMC-GNE2 datasheet, CY9AF315NAPMC-GNE2 pinout, CY9AF315NAPMC-GNE2 application, or CY9AF315NAPMC-GNE2 equivalent, key selection criteria include its dual-bank SRAM architecture for concurrent code/data access, hardware flow control support on UART channel 4, 16-channel 12-bit ADC with FIFO and priority scanning, built-in USB PLL, and 83 GPIOs in 100-pin LQFP package - all validated for industrial-grade reliability and low-power operation across SLEEP/TIMER/STOP modes.

Technical Context

The CY9AF315NAPMC-GNE2 implements an 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 includes zero-wait-state Flash and two independent SRAM banks (SRAM0 on I/D-code buses, SRAM1 on system bus), enabling parallel instruction fetch and data access.

Peripherals are tightly coupled to deterministic timing: the QPRC unit accepts AIN/BIN/ZIN encoder inputs with configurable edge detection and provides 16-bit position/revolution counters; the multi-function timer integrates input capture, output compare, A/D activation, and waveform generation - all synchronized to a shared clock domain for precise motor phase control and current sensing coordination.

FAQ

What is the maximum operating frequency and voltage range for CY9AF315NAPMC-GNE2?

The CY9AF315NAPMC-GNE2 operates at up to 40 MHz with a core supply voltage (VCC) range of 2.7 V to 5.5 V. Its USB I/O supply (USBVCC) must be 3.0–3.6 V when USB functionality is enabled; otherwise, it shares the VCC rail. These ratings are validated per Infineon's DC Characteristics table (Section 12.3) and apply across the full industrial temperature range (–40°C to +85°C).

Does CY9AF315NAPMC-GNE2 support hardware LIN 2.1 protocol handling?

Yes - the CY9AF315NAPMC-GNE2 includes dedicated LIN hardware blocks within its multi-function serial interface (CSIO). It supports LIN 2.1 master/slave operation, automatic break field generation (13–16 bits), break delimiter (1–4 bits), and error detection (parity, framing, overrun), all implemented in hardware without CPU intervention per Section 3.3.3 of the FM3 Peripheral Manual.

How many independent ADC modules does CY9AF315NAPMC-GNE2 integrate, and what is their resolution?

The CY9AF315NAPMC-GNE2 integrates three independent 12-bit successive approximation ADC units. Each supports scanning mode with 16-step FIFO, priority-based conversion (2-level), and hardware trigger from timer compare events. Total channel count is 16, with conversion time of 1.0 μs at 5 V supply, as specified in Section 3.4.1 of the datasheet.

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

Yes - the CY9AF315NAPMC-GNE2 features an External Bus Interface (EBI) supporting SRAM and NOR Flash devices. It provides up to 8 chip selects, 8-/16-bit data width, 25-bit addressing (up to 256 MB address space), address/data multiplexing, and external RDY signal handshake. This capability is confirmed in Section 3.10 of the datasheet and applies to the CY9AF315NAPMC-GNE2 variant.
