Product details
Overview
CY9BF528TABGL-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with dual-bank flash (1008 KB + 512 KB), 192 KB SRAM, USB 2.0 Full-Speed Device/Host, CAN 2.0A/B, and 24-channel 12-bit ADC. It operates up to 60 MHz, supports six low-power modes, and targets embedded motor control and industrial automation systems requiring integrated timing, communication, and analog interfaces.
For engineers reviewing the CY9BF528TABGL-GK7E1 datasheet, CY9BF528TABGL-GK7E1 pinout, CY9BF528TABGL-GK7E1 application, or CY9BF528TABGL-GK7E1 equivalent, this device offers verified USB/CAN coexistence, hardware CRC acceleration (CCITT CRC16 & IEEE-802.3 CRC32), dual-timer-based motor control waveforms, and 5V-tolerant GPIOs on a 176-pin LQFP package - critical for real-time I/O consolidation in space-constrained designs.
Technical Context
The CY9BF528TABGL-GK7E1 implements a deterministic Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, coupled with dual-bus SRAM architecture (SRAM0 on I/D-code bus, SRAM1 on system bus) enabling concurrent CPU and DMA access. Its clock system integrates five sources including main PLL, sub-clock (32.768 kHz), and dual CR oscillators, with Clock Supervisor (CSV) monitoring external clock integrity via built-in reference clocks.
Peripheral integration includes a multi-function serial interface supporting UART/CSIO/LIN/I²C across 16 channels, two independent 12-bit ADC units with 1.0 µs conversion time and FIFO-based scanning, and a dedicated QPRC block with configurable AIN/BIN/ZIN edge detection for encoder position tracking - all synchronized to a shared APB/AHB bus matrix with external bus interface supporting 256 MB address space.

FAQ
What is the maximum operating frequency and supported voltage range for CY9BF528TABGL-GK7E1?
The CY9BF528TABGL-GK7E1 operates at up to 60 MHz and supports a wide VCC supply range of 2.7 V to 5.5 V. USB functionality requires USBVCC between 3.0 V and 3.6 V when active, while GPIO operation remains valid across the full 2.7–5.5 V range. This flexibility enables direct interfacing with both 3.3 V and 5 V legacy peripherals without level-shifting.
Does CY9BF528TABGL-GK7E1 include hardware debug support, and what interface is used?
Yes, it features Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards, supporting full breakpoint, watchpoint, and real-time trace via Embedded Trace Macrocell (ETM). No external debug adapter is required beyond standard SWD-capable programmers like Segger J-Link or ST-Link v2.1, enabling seamless integration into CI/CD toolchains.
How does the dual-bank flash architecture enable firmware updates without system interruption?
The dual-bank flash (ROM0 + ROM1) allows one bank to execute code while the other is erased and reprogrammed. Bootloader logic can validate new firmware in the inactive bank before remapping the vector table and initiating a warm reset - achieving zero-downtime field updates essential for unattended industrial equipment and smart grid infrastructure.
Can CY9BF528TABGL-GK7E1 operate in deep sleep modes while maintaining RTC and RAM content?
Yes, in Deep standby RTC mode, the device retains RTC operation and optionally preserves SRAM contents using backup power (VBAT), drawing only ~1.2 µA typical. The RTC continues counting with leap-year correction and can generate wake-up interrupts on date/time match - ideal for battery-backed data loggers and remote sensors with multi-year deployment cycles.
