Product details
Overview
CY9BF316NPMC-G-JNE1 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 timers. It operates up to 144 MHz, features MPU, NVIC with 48 peripheral interrupts, and supports LIN 2.1, I²C, UART, and CSIO on eight serial channels - deployed in industrial motor drives and embedded motion controllers.
For engineers reviewing the CY9BF316NPMC-G-JNE1 datasheet, CY9BF316NPMC-G-JNE1 pinout, CY9BF316NPMC-G-JNE1 application, or CY9BF316NPMC-G-JNE1 equivalent, key selection criteria include Flash/SRAM partitioning, dual USB device/host capability, 12-bit ADC with FIFO, QPRC for encoder feedback, and 5 V-tolerant GPIO support in 120-pin LQFP package.
Technical Context
The CY9BF316NPMC-G-JNE1 implements a deterministic real-time execution environment via Arm Cortex-M3 r2p1 core with Memory Protection Unit and 24-bit SysTick timer. Its dual Flash architecture separates executable code (MainFlash) from configuration/data storage (WorkFlash), each with distinct wait-state behavior across 2.7–5.5 V supply and 40–144 MHz operation.
Peripheral integration centers on motor control: three Multi-function Timers provide PWM, dead-time insertion, A/D-triggered capture, and DTIF emergency stop; three QPRC units directly interface quadrature encoders; and USB host/device supports firmware updates and HMI communication without external PHY.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 |
|---|---|---|---|
| STM32F303RET6 | ARM Cortex-M4F core, 72 MHz max, 512 KB Flash, no integrated USB host, single QEI | Lacks USB host and dual QPRC - requires external USB bridge and encoder interface IC for equivalent functionality | Select when floating-point math acceleration is prioritized over USB host and multi-axis encoder support |
| RA6M3GFP | ARM Cortex-M4, 200 MHz, 1 MB Flash, USB host/device, but no QPRC - uses general-purpose timers for encoder emulation | Encoder position resolution limited by software-based counting - increases CPU load and reduces real-time margin vs. hardware QPRC | Select when higher clock speed and larger Flash are critical, and encoder count rates remain below 100 kpps |
Compared with STM32F303RET6 and RA6M3GFP, CY9BF316NPMC-G-JNE1 uniquely integrates USB host/device, triple QPRC, and DTIF in a single 120-pin LQFP - reducing system-level component count and improving motor control determinism without sacrificing field-upgrade capability.

FAQ
What is the maximum operating frequency and supported voltage range?
The CY9BF316NPMC-G-JNE1 operates up to 144 MHz with a supply voltage range of 2.7 V to 5.5 V on VCC. USB I/O requires USBVCC between 3.0 V and 3.6 V when the USB interface is active; otherwise, USBVCC may be tied to VCC. These specifications are validated per datasheet Section 12.2 and apply across commercial temperature range (–40°C to +85°C).
Does this MCU support USB device and host modes simultaneously?
No - the USB interface supports device mode and host mode, but not concurrently. The mode is selected at initialization via USBCTL register configuration. Device mode uses internal pull-up on USB_DP; host mode requires external VBUS detection and SOF generation. Both modes share the same USB_DP/DM pins and endpoint resources per Section 8.3 of the datasheet.
How many independent quadrature encoder interfaces does it provide?
The CY9BF316NPMC-G-JNE1 integrates three independent Quadrature Position/Revolution Counters (QPRC), each with dedicated AIN/BIN/ZIN inputs, 16-bit position and revolution counters, and two 16-bit compare registers. This enables simultaneous monitoring of up to three motors or multi-turn axes without CPU intervention, as specified in Section 18 of the FM3 Peripheral Manual.
Is the WorkFlash memory suitable for EEPROM-like data logging?
Yes - WorkFlash (32 KB) supports byte/word programming and sector erase, with endurance rated for ≥100,000 write/erase cycles. Its separate wait-state profile (0-cycle up to 40 MHz) ensures low-latency parameter updates during runtime. Unlike MainFlash, WorkFlash shares security protection but is optimized for frequent rewrites of calibration data and operational logs.
