Product details
Overview
CY9BF116NPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for embedded motor control and industrial automation. 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 12-bit ADCs (16 channels total), eight base timers, three QPRC units, and LIN/UART/I²C/CSIO serial interfaces. It is used in brushless DC motor drives requiring real-time position sensing and PWM generation.
For engineers reviewing the CY9BF116NPMC-G-JNE2 datasheet, CY9BF116NPMC-G-JNE2 pinout, CY9BF116NPMC-G-JNE2 application, or CY9BF116NPMC-G-JNE2 equivalent, key selection criteria include its 144 MHz Cortex-M3 core, dual ADC support with FIFO, QPRC with AIN/BIN/ZIN edge configuration, LIN 2.1 compliance, and 2.7–5.5 V wide-supply operation across industrial temperature range.
Technical Context
This MCU implements a deterministic real-time architecture optimized for motor control: the three Quadrature Position/Revolution Counters (QPRC) directly interface encoder signals with configurable edge detection on AIN/BIN/ZIN pins, while eight base timers provide synchronized 16-/32-bit PWM, PPG, and PWC outputs with dead-time insertion. The dual watchdog system-hardware (CR oscillator-backed) and software-ensures fail-safe operation in safety-critical motion systems.
The memory subsystem uses physically separate buses: SRAM0 connects to I-code/D-code buses for instruction/data cache coherency, SRAM1 sits on the system bus for DMA-peripheral access; Flash Accelerator enables zero-wait-state execution up to 72 MHz and maintains equivalent performance beyond via trace buffer-assisted prefetching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, up to 144 MHz - delivers deterministic interrupt latency and Thumb-2 code density for compact firmware in resource-constrained motor controllers. |
| Flash Memory | 512 KB MainFlash + 32 KB WorkFlash - supports dual-bank firmware updates and secure code protection shared between banks. |
| SRAM | 64 KB total (32 KB SRAM0 + 32 KB SRAM1) - enables concurrent CPU execution and DMA transfers without bus contention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz max, 256 KB Flash, no QPRC - uses general-purpose timers for quadrature decoding. | Lacks dedicated QPRC hardware; requires CPU cycles for position interpolation and increases jitter in high-speed commutation. | Prefer when floating-point math or DSP extensions are needed, but avoid where sub-microsecond QPRC response is mandatory. |
| RA6M3GFP | ARM Cortex-M4, 200 MHz, 1 MB Flash, 384 KB SRAM, includes QEI peripheral - supports 32-bit position counter but no built-in revolution counter. | Requires external logic or firmware to track full revolutions beyond 32-bit wrap; lacks LIN 2.1 hardware support. | Choose for higher clock headroom and larger memory, but only if LIN is replaced with CAN or UART-based diagnostics. |
Compared with STM32F303VCT6 and RA6M3GFP, CY9BF116NPMC-G-JNE2 uniquely combines LIN 2.1 compliance, triple QPRC with revolution counting, and Flash Accelerator for deterministic motor control - making it optimal for cost-sensitive, encoder-based BLDC applications requiring certified automotive communication.

FAQ
What is the maximum operating frequency of the CY9BF116NPMC-G-JNE2 core?
The Arm Cortex-M3 core operates up to 144 MHz, enabled by the Main PLL with input from either an external 4–48 MHz crystal or the internal 4 MHz CR oscillator. Flash Accelerator ensures zero-wait-state execution up to 72 MHz and maintains effective performance beyond that via trace-buffer-assisted prefetching.
Does CY9BF116NPMC-G-JNE2 support LIN 2.1 in hardware?
Yes - it includes dedicated LIN hardware modules compliant with LIN 2.1 specification, supporting both master and slave modes, configurable break field (13–16 bits), break delimiter (1–4 bits), and automatic error detection including parity, framing, and overrun errors.
How many independent QPRC units does this MCU integrate?
CY9BF116NPMC-G-JNE2 integrates three independent Quadrature Position/Revolution Counters. Each provides a 16-bit position counter, a 16-bit revolution counter, and two 16-bit compare registers - enabling simultaneous monitoring of multiple encoder axes without CPU load.
Is the device qualified for automotive applications?
While not AEC-Q100 certified out-of-box, CY9BF116NPMC-G-JNE2 is widely deployed in automotive HVAC and body control modules. Its design includes LIN 2.1 compliance, 100 kHz hardware watchdog, clock supervisor (CSV), dual LVD stages, and -40°C to +105°C industrial temperature grade - meeting key functional safety prerequisites for non-safety-critical automotive subsystems.
