Product details
Overview
CY9BF315NPMC-G-JNK1E2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB MainFlash, 32 KB WorkFlash, 64 KB SRAM, USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including QPRC, multi-function timers, and LIN/UART/I²C/CSIO serial interfaces. It operates up to 144 MHz, supports 2.7–5.5 V supply, and targets embedded motor control, industrial automation, and automotive body electronics.
For engineers reviewing the CY9BF315NPMC-G-JNK1E2 datasheet, CY9BF315NPMC-G-JNK1E2 pinout, CY9BF315NPMC-G-JNK1E2 application, or CY9BF315NPMC-G-JNK1E2 equivalent, key selection criteria include Flash/SRAM partitioning, USB dual-role capability, 12-bit ADC timing (1.0 µs @ 5 V), 16-channel analog input support, and 103 GPIOs in 120-pin LQFP package with 5 V-tolerant I/O.
Technical Context
This MCU implements a dual-bank Flash architecture-MainFlash (512 KB, zero-wait-state up to 72 MHz with accelerator) and WorkFlash (32 KB, wait-state dependent on frequency)-enabling robust firmware updates and code protection. Its memory subsystem includes two independent SRAM banks (SRAM0/SRAM1, 32 KB each) connected to I-code/D-code and system buses respectively for deterministic real-time execution.
The peripheral set is optimized for motion control: three QPRC channels for encoder position tracking, three multi-function timers with dead-time insertion and DTIF emergency stop, and LIN 2.1-compliant transceivers with configurable break field (13–16 bit) and delimiter (1–4 bit). USB operation uses an integrated PLL fed by the main clock, supporting full-speed device (6 endpoints, 256-byte EP1 buffer) and host (256-byte packet, auto-connect detection) modes.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF315NPMC-G-JNK1E2 achieves up to 144 MHz core frequency using the main PLL with an external crystal (4–48 MHz) as input. The Flash accelerator enables zero-wait-state execution up to 72 MHz; above that, the accelerator maintains equivalent performance through prefetch and trace buffer mechanisms, ensuring deterministic timing for real-time control loops.
Does this MCU support LIN communication without external transceivers?
Yes - the MCU integrates LIN protocol logic (Rev. 2.1) directly into its serial interface modules. However, a physical-layer LIN transceiver (e.g., TLE7259-3GE) is still required on the board to drive the 12 V bus. The MCU handles frame generation, checksum calculation, break field timing (13–16 bit), and error detection internally.
How many independent ADC modules are implemented and what is their resolution?
The device contains one 12-bit successive approximation register (SAR) ADC with up to 16 input channels. It is not multiple independent ADCs but a single high-speed module supporting scanning mode (16-step FIFO) and priority conversion (4-step FIFO), delivering 1.0 µs conversion time at 5 V supply - sufficient for current sensing in motor control applications.
Is USB host functionality supported, and what peripherals can be connected?
Yes - the integrated USB host controller supports Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) devices. It can connect HID-class peripherals (keyboards, mice), CDC-class modems, mass storage devices (USB flash drives), and custom class devices. Automatic device connect/disconnect detection and IN/OUT token handshake handling are implemented in hardware.
