Infineon Technologies CY96F673ABPMC1-GS-UJE2

Overview

CY96F673ABPMC1-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with integrated CAN 2.0A/B interface, 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 and targets automotive body control, industrial motor drives, and smart sensor nodes requiring real-time CAN communication and low-power operation.

For engineers reviewing the CY96F673ABPMC1-GS-UJE2 datasheet, CY96F673ABPMC1-GS-UJE2 pinout, CY96F673ABPMC1-GS-UJE2 application, or CY96F673ABPMC1-GS-UJE2 equivalent, key selection criteria include its 32-message-object CAN controller with ISO16845 certification, 16-bit PPGs for stepper motor timing, RTC with clock calibration, LIN-capable USARTs, and hardware debugger with 6 hardware breakpoints - all in an LQFP-64 package.

Technical Context

The CY96F673ABPMC1-GS-UJE2 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes. Its clock system supports independent domain selection: CPU clock (up to 32MHz via PLL), peripheral clock (configurable via prescalers), and subclock (32.768kHz) for RTC - enabling simultaneous high-speed processing and ultra-low-power sleep modes.

Peripheral integration includes two 16-bit free-running timers, three 16-bit reload timers, four 16-bit input capture units, four 16-bit programmable pulse generators (with timing point capture), and a dedicated stepping motor controller with two synchronized 8/10-bit PWM channels per SMC unit. The CAN module operates up to 1Mbps with FIFO mode, loop-back test, and disabled automatic retransmission for time-triggered use cases.

FAQ

What is the maximum operating frequency of the CY96F673ABPMC1-GS-UJE2 CPU?

The CPU achieves up to 32MHz operation using the internal PLL multiplier (×1 to ×8) driven by a 4–8MHz external ceramic resonator or crystal. This yields a minimum instruction cycle time of 31.2ns. The PLL is fully configurable via register settings and supports dynamic switching between clock sources without reset.

Does the CY96F673ABPMC1-GS-UJE2 support LIN communication?

Yes - it integrates two LIN-capable USARTs (SCI/LIN), with one channel supporting automatic LIN header transmission/reception and 16-byte RX/TX FIFO. LIN functionality operates in both master and slave modes, and extended LIN protocol support reduces CPU interrupt load during frame handling.

How does the dual-operation Flash memory work in practice?

Dual-operation Flash allows concurrent read access from one bank while programming or erasing the other. This enables safe over-the-air (OTA) firmware updates: the active application runs from Bank A while new code is written to Bank B, then a controlled bank swap occurs at a safe execution point - eliminating system downtime during updates.

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

Yes - the integrated Stepping Motor Controller (SMC) provides two independent channels, each with four high-current outputs and two synchronized 8/10-bit PWMs. It supports full-step, half-step, and microstepping via software-controlled phase sequencing and includes dedicated power supply pins (VSMC) for external high-current drivers or direct coil drive.
