Product details
Overview
CY9BF115NPQC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for embedded motor control and industrial automation systems. It operates up to 144 MHz, integrates 512 KB MainFlash with Flash Accelerator, 32 KB WorkFlash, 64 KB SRAM (split into SRAM0/SRAM1), and features dual A/D converters (12-bit, 16-channel, 1.0 µs conversion), LIN/UART/I²C/CSIO interfaces, and QPRC for encoder position sensing.
For engineers reviewing the CY9BF115NPQC-G-JNE2 datasheet, CY9BF115NPQC-G-JNE2 pinout, CY9BF115NPQC-G-JNE2 application, or CY9BF115NPQC-G-JNE2 equivalent, key selection criteria include real-time motor timing (PPG/PWM timers), on-chip code protection, 2.7–5.5 V operation, RTC with leap-year support, and SWJ-DP debug with ETM trace capability.
Technical Context
The CY9BF115NPQC-G-JNE2 implements an Arm Cortex-M3 r2p1 core with MPU and NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem uses two independent Flash banks (MainFlash + WorkFlash) and dual-bus SRAM architecture - SRAM0 on I-code/D-code buses, SRAM1 on system bus - enabling concurrent CPU and DMA access.
Peripheral integration includes three multi-function timers with PWM, dead-time insertion, and A/D activation triggers; three QPRC channels for quadrature encoder interfacing; and a dual watchdog system (hardware clocked by 100 kHz CR oscillator, software configurable). Clock supervision (CSV) monitors external oscillator failure or frequency anomaly with reset/interrupt response.

FAQ
What is the maximum operating frequency and supported clock sources?
The CY9BF115NPQC-G-JNE2 operates up to 144 MHz using its main PLL, which accepts input from either a 4–48 MHz external crystal or the 4 MHz internal CR oscillator. Five clock sources are available: two external oscillators (main and sub), two internal CR clocks (4 MHz high-speed and 100 kHz low-speed), and the main PLL - all dynamically switchable at runtime without reset.
Does this MCU support secure firmware updates and code protection?
Yes. The device implements Flash security functions shared between MainFlash and WorkFlash, including read-out protection and write protection per sector. The Memory Protection Unit (MPU) enforces privilege-level access control, and the CRC32 accelerator verifies firmware image integrity before execution - meeting requirements for IEC 61508 SIL2 functional safety applications.
How many independent A/D converters does it have, and what is their performance?
The CY9BF115NPQC-G-JNE2 integrates three independent 12-bit successive approximation register (SAR) A/D converters, supporting up to 16 input channels. Each converter achieves 1.0 µs conversion time at 5 V supply, with priority-based and scanning modes plus built-in FIFOs (16-step for scan, 4-step for priority) - enabling synchronized multi-channel sampling for motor phase current reconstruction.
Is external memory interface supported, and what devices can it connect to?
Yes. The External Bus Interface supports SRAM, NOR Flash, and NAND Flash devices with up to 8 chip selects, 8-/16-bit data width, and 25-bit addressing (256 MB address space). It supports address/data multiplexing and external RDY input for handshake timing - enabling direct connection to external program memory or FPGA co-processors in PLC and HMI applications.
