Product details
Overview
CY9BF168NPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M4F microcontroller with 1024 KB MainFlash, 64 KB SRAM0, and integrated motor control peripherals including dual QPRC, 8-channel base timers, and LIN/UART/I²C/CSIO interfaces. It operates up to 160 MHz with FPU, MPU, and hardware CRC acceleration, targeting real-time embedded motor control systems in industrial drives and HVAC blowers.
For engineers reviewing the CY9BF168NPMC-GNE2 datasheet, CY9BF168NPMC-GNE2 pinout, CY9BF168NPMC-GNE2 application, or CY9BF168NPMC-GNE2 equivalent, key selection criteria include Flash/SRAM partitioning (MainFlash + 32 KB WorkFlash), 12-bit ADC with 24 channels and 0.5 µs conversion time, 5V-tolerant GPIO support, RTC with leap-year handling, and dual watchdog timers (hardware + software) for functional safety compliance.
Technical Context
The CY9BF168NPMC-GNE2 implements a deterministic real-time architecture centered on the ARM Cortex-M4F core (r0p1 revision) with tightly coupled memory subsystems: MainFlash (1024 KB, zero-wait up to 72 MHz), WorkFlash (32 KB, configurable wait states), and three independent SRAM banks (SRAM0: 64 KB, SRAM1/SRAM2: 32 KB each). Its peripheral set includes DSTC (128-channel descriptor-based DMA), dual QPRC for encoder position tracking, and multi-function timers supporting PWM, PPG, and dead-time insertion.
Timing integrity is enforced via Clock Supervisor (CSV) monitoring external oscillator failure/frequency deviation, Low-Voltage Detector (LVD1/LVD2) with interrupt/reset options, and six low-power modes including Deep Standby RTC with optional RAM retention. The device supports external bus interface (up to 256 MB address space) and SD card host controller compliant with SD Host Controller Standard v3.00.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY9BF168NPMC-GNE2 achieves 160 MHz maximum operation using its internal Main PLL, which multiplies an external 4–48 MHz crystal input. The PLL output feeds the core, memory, and peripheral clocks. Flash accelerator enables zero-wait-state execution up to 72 MHz; above that, the accelerator maintains equivalent performance by prefetching and buffering instructions.
Does this MCU support functional safety standards like IEC 61508 or ISO 26262?
While CY9BF168NPMC-GNE2 includes safety-oriented features-dual watchdog timers (hardware and software), Clock Supervisor, MPU, LVD1/LVD2, and ECC-capable memories-it is not pre-certified to IEC 61508 SIL3 or ISO 26262 ASIL-B. Customers must perform their own FMEDA, diagnostic coverage analysis, and qualification testing per target application requirements.
How does the WorkFlash differ from MainFlash in usage and protection?
WorkFlash (32 KB) is a separate Flash bank optimized for frequent firmware updates and parameter storage. It shares the same code protection mechanism as MainFlash but uses configurable wait states (0–6 cycles) scaled to operating frequency. Unlike MainFlash, WorkFlash supports faster erase/write cycles and is commonly used for bootloader staging or runtime configuration tables.
Can the SD card interface operate in 4-bit mode and what protocol versions does it support?
Yes, the SD card interface supports both 1-bit and 4-bit data bus widths. It complies with SD Physical Layer Specification v3.01, SDIO Specification v3.00, and SD Host Controller Standard v3.00-enabling compatibility with SDHC and SDXC cards up to UHS-I speeds when paired with appropriate external level-shifting and signal integrity design.
