Infineon Technologies CY9BF117TBGL-GK7E1

Overview

CY9BF117TBGL-GK7E1 from Cypress Semiconductor is a 32-bit ARM® Cortex®-M3 microcontroller in the FM3 family, designed for high-performance embedded motor control and industrial automation. It operates up to 144 MHz, integrates 1 MB Flash and 128 KB SRAM (64 KB SRAM0 + 64 KB SRAM1), supports LIN 2.1, UART, I²C, and CSIO interfaces, and features dual watchdog timers, hardware CRC accelerator, and QPRC for encoder position sensing - deployed in brushless DC motor drives and factory I/O controllers.

For engineers reviewing the CY9BF117TBGL-GK7E1 datasheet, CY9BF117TBGL-GK7E1 pinout, CY9BF117TBGL-GK7E1 application, or CY9BF117TBGL-GK7E1 equivalent, key selection criteria include its 176-pin LQFP package with 154 fast I/Os, 32-channel 12-bit ADC with 1.0 µs conversion time at 5 V, dual 16-/32-bit base timers, and dedicated motor control peripherals including dead-time insertion and DTIF interrupt.

Technical Context

The CY9BF117TBGL-GK7E1 implements an ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its on-chip memory architecture separates instruction/data access (SRAM0 on I-code/D-code buses) from system bus traffic (SRAM1), enabling deterministic real-time execution.

Peripheral subsystems are tightly coupled to the CPU via dedicated buses: the 8-channel DMA controller operates independently of the CPU; the QPRC block accepts AIN/BIN/ZIN quadrature inputs with configurable edge detection and dual 16-bit counters; and the multi-function serial interface provides per-channel mode selection among UART, CSIO, LIN, and I²C - with LIN master/slave support and programmable break field (13–16 bit) and delimiter (1–4 bit).

Key Specifications

Pinout & Package

This device is housed in a 176-pin LQFP package (24 × 24 mm, 0.5 mm pitch) with exposed thermal pad, rated for industrial temperature range (–40°C to +85°C). Pin assignment includes 154 general-purpose I/Os, many 5 V tolerant, and dedicated function pins for external bus interface, clock inputs, reset, JTAG/SW debug, and analog inputs.

FAQ

Does CY9BF117TBGL-GK7E1 support debugging via SWD or only JTAG?

It supports Serial Wire Debug (SWD) exclusively through the SWJ-DP interface, which multiplexes SWD and JTAG signals on shared pins (TMS, TCK, TDO, TDI, nTRST). SWD mode is enabled by default and offers faster, lower-pin-count debugging compared to full JTAG, while maintaining full ETM trace capability.

What is the maximum operating frequency when using the internal CR oscillators?

The built-in high-speed CR oscillator runs at 4 MHz and can serve as a fallback clock source, but it does not support PLL multiplication. Therefore, maximum CPU frequency under internal CR clock is limited to 4 MHz - intended only for safe-mode operation or low-power initialization before switching to main crystal or PLL.

Can the 12-bit ADC perform simultaneous sampling across multiple channels?

No - the three 12-bit ADC units operate independently but do not support hardware-triggered simultaneous sampling. Each unit performs successive approximation conversion sequentially; however, priority and scan modes allow deterministic interleaving of conversions across up to 32 channels with FIFO buffering (16-step for scan, 4-step for priority).

Is the Flash memory accelerator active by default after reset?

Yes - the Flash Accelerator System is enabled automatically after power-on reset and remains active unless explicitly disabled via the FASCR register. It dynamically inserts wait states only when required (e.g., above 72 MHz), and includes a 16 KB trace buffer to reduce instruction fetch stalls during branch-heavy code execution.
