Product details
Overview
CY9AF312KPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 128 KB MainFlash, 32 KB WorkFlash, 16 KB SRAM (8 KB SRAM0 + 8 KB SRAM1), USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including 8-channel 12-bit ADC (1.0 μs conversion @5 V), QPRC, and multi-function timers. It targets embedded motor control and industrial automation systems requiring real-time responsiveness and mixed-signal integration.
For engineers reviewing the CY9AF312KPMC1-G-JNE2 datasheet, CY9AF312KPMC1-G-JNE2 pinout, CY9AF312KPMC1-G-JNE2 application, or CY9AF312KPMC1-G-JNE2 equivalent, key selection criteria include USB dual-role capability, 40 MHz max CPU frequency, 2.7–5.5 V supply range, RTC with leap-year support, and 36 GPIO with port relocation and 5V-tolerant pins.
Technical Context
This MCU implements the 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 two independent Flash banks (MainFlash and WorkFlash) with zero-wait-state operation and shared code protection, and dual-bus-connected SRAM banks optimized for instruction/data separation.
The peripheral set is purpose-built for motion control: dual 12-bit ADCs with FIFO-based scanning and priority conversion, Quadrature Position/Revolution Counter (QPRC) with configurable A/B/Z input edges and 16-bit position/revolution counters, and multi-function timers supporting PWM, dead-time insertion, DC chopper waveform generation, and A/D activation triggers - all synchronized to a common clock domain.

FAQ
What is the maximum operating frequency of the CY9AF312KPMC1-G-JNE2?
The CY9AF312KPMC1-G-JNE2 operates at up to 40 MHz using its ARM Cortex-M3 core. This frequency is achievable with the main clock sourced from an external 4–48 MHz crystal or oscillator, or via the internal high-speed CR oscillator (4 MHz) multiplied by the main PLL. The datasheet specifies AC characteristics and timing margins validated at this maximum speed.
Does this MCU support USB host functionality without external components?
Yes. The CY9AF312KPMC1-G-JNE2 integrates a full USB 2.0 Full-Speed host controller with built-in PLL, endpoint buffers, and automatic device connect/disconnect detection. It supports bulk, interrupt, and isochronous transfers and can enumerate low- and full-speed USB peripherals directly - no external PHY or hub IC is required for basic host operation.
How many independent ADC modules does this device have, and what is their resolution?
The device contains two independent 12-bit successive approximation register (SAR) ADC units, each supporting up to 8 input channels. Each ADC achieves a 1.0 μs conversion time at 5 V supply, with configurable priority levels, scanning modes, and dedicated FIFOs (16-step for scan, 4-step for priority) - enabling simultaneous sampling of multiple motor phase currents or sensor signals.
Is the QPRC block capable of handling both position and revolution counting simultaneously?
Yes. The Quadrature Position/Revolution Counter (QPRC) provides two independent 16-bit counters: one for position (incrementing/decrementing on A/B edge transitions) and one for revolutions (incrementing on Z-index pulses). Both counters operate concurrently, share configurable input filters on AIN/BIN/ZIN pins, and support compare-match interrupts - essential for absolute position tracking in servo systems.
