Infineon Technologies CY96F673RBPMC1-GS-UJE1

Overview

CY96F673RBPMC1-GS-UJE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with integrated CAN 2.0A/B controller, 12-channel 8/10-bit SAR ADC, dual-operation Flash (128.5KB + 32KB), 48–50 GPIO, and on-chip voltage regulator supporting 2.7V–5.5V operation. It delivers 32MHz CPU speed via internal PLL (×1–×8) from 4–8MHz external resonator, achieving 31.2ns instruction cycle time for real-time motor control and automotive body electronics.

For engineers reviewing the CY96F673RBPMC1-GS-UJE1 datasheet, CY96F673RBPMC1-GS-UJE1 pinout, CY96F673RBPMC1-GS-UJE1 application, or CY96F673RBPMC1-GS-UJE1 equivalent, key selection criteria include CAN bit rate up to 1Mbps, 32 message objects with maskable interrupts, stepping motor controller with two synchronized 8/10-bit PWMs per channel, and ISO16845-certified CAN compliance for automotive ECU designs.

Technical Context

The CY96F673RBPMC1-GS-UJE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes optimized for embedded control. Its clock tree supports independent domain selection: CPU runs at up to 32MHz (PLL-derived), while peripherals operate at configurable frequencies using main, sub (32.768kHz), or RC (100kHz/2MHz) clocks.

It integrates a dedicated stepping motor controller with four high-current outputs per channel, internal prescaling for PWM clock (1, 1/4, 1/5, 1/6, 1/8, 1/10, 1/12, 1/16), and separate power supply for drivers. The CAN interface includes programmable loop-back mode, disabled automatic retransmission for time-triggered operation, and FIFO concatenation across 32 message objects.

FAQ

What is the maximum operating frequency of the CY96F673RBPMC1-GS-UJE1 CPU?

The CPU achieves a maximum operating frequency of 32MHz using the internal PLL with a ×8 multiplication factor applied to a 4MHz external resonator. This yields a minimum instruction cycle time of 31.2ns. Operation at 32MHz requires proper PCB layout for the resonator circuit and adherence to the recommended load capacitance and drive level specifications in the datasheet.

Does the CY96F673RBPMC1-GS-UJE1 support CAN FD or only classical CAN?

The CY96F673RBPMC1-GS-UJE1 supports only Classical CAN (CAN 2.0A/B), not CAN FD. It implements ISO16845-certified CAN 2.0B with bit rates up to 1Mbps and 32 configurable message objects. CAN FD features such as flexible data-rate, extended data length, and CRC enhancements are not present in this device's CAN peripheral.

How many ADC channels does the CY96F673RBPMC1-GS-UJE1 have, and what resolutions are supported?

The device integrates a 12-channel SAR ADC supporting both 8-bit and 10-bit conversion resolutions. Input channels AN12–AN23 are mapped to physical pins, and conversions can be triggered by software, reload timers, PPG events, or external signals. The ADC includes range comparator and pulse detection functions for real-time threshold monitoring without CPU intervention.

Is the stepping motor controller capable of driving bipolar stepper motors directly?

Yes-the integrated stepping motor controller provides four high-current outputs per channel, supporting unipolar and bipolar stepper motor configurations. Each channel includes dedicated power supply pins (Vsmc) and internal PWM generators synchronized to enable full-step, half-step, and microstepping control without external H-bridge ICs, provided external current-limiting resistors and flyback diodes are used per datasheet guidelines.
