Product details
Overview
CY9BF166RBGL-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 requiring deterministic timing, code security, and low-power RTC operation.
For engineers reviewing the CY9BF166RBGL-GK7E1 datasheet, CY9BF166RBGL-GK7E1 pinout, CY9BF166RBGL-GK7E1 application, or CY9BF166RBGL-GK7E1 equivalent, key selection criteria include Flash accelerator performance at >72 MHz, dual watchdog architecture (hardware + software), 24-channel 12-bit ADC with 0.5 µs conversion, SD card interface compliance with SD Host Controller Standard v3.00, and 5V-tolerant I/O on selected pins.
Technical Context
This MCU implements a dual-Flash architecture (MainFlash + WorkFlash) with independent wait-state control per memory region and hardware scramble support for external bus areas. The DSTC (Descriptor System Data Transfer Controller) enables CPU-offload DMA-like transfers across 128 channels using memory-resident descriptors-critical for high-throughput sensor or motor feedback data pipelines.
Its clock system integrates five sources (4–48 MHz main oscillator, 32.768 kHz sub-clock, 4 MHz/100 kHz CR oscillators, and Main PLL) with Clock Supervisor (CSV) monitoring external oscillator failure and frequency anomaly. Reset logic includes INITX-pin assertion, power-on, software, watchdog, LVD, and CSV-triggered reset paths-ensuring robust fault recovery in industrial environments.
Key Specifications

Pinout & Package
The CY9BF166RBGL-GK7E1 is housed in a 120-pin LQFP package (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions are defined across four dedicated port groups (P0–P3), supporting peripheral relocation and 5V-tolerant I/O on designated pins (e.g., P0_0–P0_7, P1_0–P1_7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Core power supply / ground | Dual 2.7–5.5 V domains support mixed-voltage interfacing; decoupling required per datasheet layout guidelines. |
| XTAL / EXTAL | Main crystal oscillator inputs | Supports 4–48 MHz external crystals; used with Main PLL for high-accuracy system clock generation. |

| INITX | External reset input | Active-low asynchronous reset pin-assertion forces full system reset regardless of power mode or clock state. |
| P0_0–P0_7 | General-purpose I/O / peripheral multiplex | 5V-tolerant; configurable as UART0_TX/RX, CSIO0, LIN0, or QPRC_A/B/Z inputs-enables direct connection to legacy 5V sensors or transceivers. |
| SWDIO / SWCLK | Serial Wire Debug interface | Two-pin JTAG/SWD debug port supporting flash programming, real-time trace via ETM, and breakpoint debugging without halting CPU. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Flash Architecture | MainFlash (1024 KB) + WorkFlash (32 KB) with independent wait-state control and shared code protection-enables secure over-the-air firmware updates without runtime interruption. |
| Descriptor-Based DSTC | 128-channel descriptor-driven data mover bypassing CPU-reduces CPU load by >40% in high-bandwidth ADC-to-SD-card logging or motor feedback streaming. |
| Motor Control Timer Suite | 2× Multi-function Timers with dead-time insertion, DTIF emergency stop, A/D activation triggers, and waveform generation-eliminates need for external gate drivers or FPGA glue logic. |
| Scramble Function for External Bus | Configurable per 4 MB region (0x6000_0000–0xDFFF_FFFF) with two independent keys-protects external NOR/NAND/SDRAM contents against physical probing or replay attacks. |
| VBAT-Powered RTC & Backup Registers | 32-byte backup registers retain configuration across power cycles; RTC continues counting from VBAT (2.7–5.5 V) during deep standby-enables time-stamped event logging with zero battery drain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Higher core frequency (480 MHz), dual-core (Cortex-M7/M4), no integrated LIN PHY; requires external transceiver. | Targets high-end motor drives with AI inference; lacks native LIN 2.1 support and VBAT RTC retention. | Select when needing >200 DMIPS compute or dual-core isolation; avoid if LIN bus integration or battery-backed RTC is mandatory. |
| RA6M5L20FB | Same Cortex-M4F core, 240 MHz max, 1 MB Flash, but no QPRC or motor-specific timers; uses Renesas' TrustZone instead of MPU. | Focused on secure IoT edge nodes; lacks quadrature encoder interface and motor emergency stop (DTIF) interrupt. | Select for TLS-secured cloud-connected devices; avoid for motion control where QPRC and DTIF are critical. |
Compared with STM32H743VI and RA6M5L20FB, CY9BF166RBGL-GK7E1 uniquely combines LIN 2.1 PHY integration, VBAT-powered RTC with 32-byte backup registers, and hardware-accelerated scramble for external memory-making it optimal for cost-sensitive, safety-aware motor and automotive body control designs where peripheral consolidation reduces PCB area and validation effort.

FAQ
What is the maximum operating temperature range for CY9BF166RBGL-GK7E1?
The CY9BF166RBGL-GK7E1 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per JEDEC JESD22-A104 and confirmed in Section 12.2 of the datasheet (Rev. *H). Operation beyond this range may cause timing violations in Flash access or SRAM retention loss.
Does CY9BF166RBGL-GK7E1 support secure boot with cryptographic signature verification?
No. While the device includes Flash security functions (code protection lock bits) and CRC accelerators, it does not implement hardware-based secure boot with public-key signature verification (e.g., ECDSA or RSA). Secure firmware update must be implemented in software using external trusted elements or host-side authentication.
Can the WorkFlash memory be used for EEPROM emulation?
Yes. The 32 KB WorkFlash supports individual sector erase (4 KB sectors) and byte-programmable writes, making it suitable for EEPROM emulation. Datasheet Section 9 confirms endurance of ≥100,000 write/erase cycles per sector, with wear-leveling software required to distribute writes across sectors.
Is the SD card interface compliant with UHS-I or SDXC standards?
No. The SD card interface complies only with SD Host Controller Standard v3.00 (2010), supporting SDSC and SDHC cards up to 32 GB. It does not support UHS-I timing modes, SDXC addressing (exFAT), or SDR104 speeds. Maximum data rate is limited to 25 MB/s in 4-bit mode per specification limits.
