Infineon Technologies CY9BF318TPMC-GK7CGFKE1

Overview

CY9BF318TPMC-GK7CGFKE1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, USB 2.0 Full-Speed device/host interface, 32-channel 12-bit ADC (1.0 μs conversion), and motor control peripherals including QPRC, multi-function timers, and PWM. It operates up to 144 MHz, supports 2.7–5.5 V supply, and targets embedded motor control and industrial automation.

For engineers reviewing the CY9BF318TPMC-GK7CGFKE1 datasheet, CY9BF318TPMC-GK7CGFKE1 pinout, CY9BF318TPMC-GK7CGFKE1 application, or CY9BF318TPMC-GK7CGFKE1 equivalent, key selection factors include its dual USB channel support (device + host), integrated Flash accelerator enabling zero-wait-state access at ≤72 MHz, MPU-enhanced system reliability, and 154 fast I/O pins in LQFP-176 package.

Technical Context

This MCU implements the ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its clock system integrates five sources - main oscillator (4–48 MHz), sub-clock (32.768 kHz), high-speed/low-speed internal CR oscillators, and Main PLL - managed by Clock Supervisor (CSV) for external clock failure detection.

The peripheral architecture includes three independent A/D converters (12-bit SAR, 1.0 μs @ 5 V), eight-channel DMA with 32-bit addressing, and dedicated motor control blocks: QPRC (3 channels, 16-bit position/revolution counters), multi-function timers with dead-time insertion and DTIF interrupt, and base timers configurable as PWM, PPG, reload, or PWC modes.

FAQ

What is the maximum operating frequency and how is it achieved?

The CY9BF318TPMC-GK7CGFKE1 achieves up to 144 MHz using its Main PLL, which accepts input from either the 4–48 MHz main oscillator or the 4 MHz high-speed internal CR oscillator. The Flash Accelerator ensures zero-wait-state execution up to 72 MHz; above that, the accelerator maintains equivalent performance through prefetch and buffering, verified in Rev.*D datasheet Section 12.4.4–12.4.5.

Does this MCU support USB host functionality, and what protocols are compatible?

Yes, it supports USB 2.0 Full-Speed and Low-Speed host mode with bulk, interrupt, and isochronous transfers. It automatically detects device connect/disconnect, handles IN/OUT token handshaking, supports up to 256-byte packets, and provides wake-up capability. This is implemented in dedicated USB host hardware blocks, distinct from the USB device channel, as confirmed in Section 3.3 of the 002-04686 datasheet.

How many ADC channels can be used simultaneously, and what is the conversion latency?

Up to 32 analog input channels can be scanned simultaneously across three independent 12-bit SAR ADC units. Each unit achieves 1.0 μs conversion time at 5 V supply, with built-in FIFOs (16-step for scan, 4-step for priority mode). Simultaneous sampling is not supported, but interleaved conversion with DMA offload enables effective real-time acquisition, as specified in Section 3.10 and Table 12.3.2.

Is the LQFP-176 package RoHS-compliant and lead-free?

Yes, the CY9BF318TPMC-GK7CGFKE1 in LQFP-176 package is RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level MSL3 and IPC/JEDEC J-STD-033 handling requirements. This is documented in Section 6.2 "Precautions for Package Mounting" and the ordering part number suffix "GK7CGFKE1", where "G" denotes green (halogen-free) and "FKE1" indicates lead-free LQFP packaging.
