Product details
Overview
CY9BF168RBGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M4F microcontroller with 1024 KB Flash, 128 KB SRAM (64+32+32), 160 MHz max CPU frequency, integrated FPU and MPU, and motor control peripherals including QPRC, multi-function timers, and LIN/UART/I²C/CSIO interfaces. It targets real-time embedded motor control systems in industrial drives and HVAC blowers.
For engineers reviewing the CY9BF168RBGL-GK7E1 datasheet, CY9BF168RBGL-GK7E1 pinout, CY9BF168RBGL-GK7E1 application, or CY9BF168RBGL-GK7E1 equivalent, key selection criteria include Flash/SRAM partitioning, dual 12-bit ADCs with FIFO, 5V-tolerant GPIO count, RTC with calendar, and SD card interface compliance with SD Host Controller Standard v3.00.
Technical Context
The CY9BF168RBGL-GK7E1 implements a dual-bank Flash architecture (MainFlash + WorkFlash) with independent wait-state control per bank-0–6 wait cycles depending on operating frequency up to 160 MHz-and shared code protection. Its memory subsystem includes three isolated SRAM banks (SRAM0 on I/D bus, SRAM1/SRAM2 on system bus) enabling deterministic real-time execution.
Peripheral integration centers on deterministic motor control: two Quadrature Position/Revolution Counters (QPRC), eight base timers supporting PWM/PPG/PWC modes, dual watchdogs (hardware + software), and DSTC with 128-channel descriptor-based DMA for off-CPU data movement between peripherals and memory-critical for sensor sampling and actuator update pipelines without CPU load.

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 |
|---|---|---|---|
| STM32H743VI | Single 2MB Flash, no WorkFlash partition; dual-core (Cortex-M7/M4); lacks native LIN PHY but supports via software stack | Targets higher-performance compute-intensive applications (e.g., AI edge inference); requires external LIN transceiver | Choose when needing >400 DMIPS or dual-core isolation; avoid if LIN 2.1 hardware support and Flash safety partitioning are mandatory |
| RA6T2 Group | 1.5MB Flash, 384KB RAM; built-in encoder interface (QE) but only one QPRC-equivalent unit; no SD host interface | Focused on cost-sensitive inverter designs with basic motion control; lacks RTC calendar and SD card logging capability | Choose for simpler BLDC drives where SD logging and leap-year RTC are unnecessary; avoid if dual QPRC or SDIO v3.00 compliance is required |
Compared with STM32H743VI and RA6T2, CY9BF168RBGL-GK7E1 uniquely combines dual-bank Flash with hardware LIN 2.1, dual QPRC, and SD host v3.00-making it optimal for industrial motor controllers requiring certified communication, position feedback redundancy, and local firmware/data storage.

FAQ
What is the maximum operating frequency and does it require external clock conditioning?
The CY9BF168RBGL-GK7E1 operates at up to 160 MHz using its internal Main PLL, which accepts 4–48 MHz external crystal input (XTAL/EXTAL). No external clock conditioner is needed-the PLL provides low-jitter system clock with dynamic frequency scaling support across all low-power modes.
Does this MCU support functional safety standards like IEC 61508 or ISO 26262?
While not ASIL-certified out-of-box, the CY9BF168RBGL-GK7E1 includes MPU, dual watchdogs, CSV, LVD, ECC-capable Flash (via accelerator), and lockstep-ready peripherals-providing foundational hardware features used in IEC 61508 SIL2 and ISO 26262 ASIL-B implementations when combined with qualified software libraries and diagnostic routines.
How many independent ADC modules are implemented and what is their conversion latency?
Three independent 12-bit SAR ADC modules are integrated. Each achieves 0.5 µs conversion time at 5 V supply, with configurable priority levels, scanning mode, and dedicated 16-step FIFO for continuous acquisition-enabling synchronized current sensing across multiple motor phases without CPU intervention.
Can the SD card interface operate in 4-bit mode and does it support SDHC/SDXC cards?
Yes-the SD card interface supports both 1-bit and 4-bit data bus widths per SD Host Controller Standard v3.00. It is compatible with SDHC (up to 32 GB) and SDXC (64 GB+) cards formatted with FAT32/exFAT, provided the host software implements the required command set and voltage switching protocol.
