Infineon Technologies CY96F673ABPMC1-GS-UJE1

Overview

CY96F673ABPMC1-GS-UJE1 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 GPIOs, 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 modules requiring ISO16845-certified CAN communication and real-time motor control.

For engineers reviewing the CY96F673ABPMC1-GS-UJE1 datasheet, CY96F673ABPMC1-GS-UJE1 pinout, CY96F673ABPMC1-GS-UJE1 application, or CY96F673ABPMC1-GS-UJE1 equivalent, key selection criteria include its 32-message-object CAN controller, dual-bank Flash for safe firmware updates, 2-channel stepping motor controller with high-current drivers, LIN-capable USARTs, and hardware watchdog with window function - all in LQFP-64 package.

Technical Context

The CY96F673ABPMC1-GS-UJE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes. Its clock tree supports independent domain selection: CPU from PLL-multiplied main clock (up to 32MHz), peripherals from main/sub/RC clocks, and RTC from 32.768kHz crystal or calibrated RC oscillator.

It integrates dedicated hardware accelerators including 4-channel 16-bit PPGs (with timing point capture and ADC trigger), 2-channel stepping motor controllers (each with two synchronized 8/10-bit PWMs and dedicated high-current drivers), and ISO16845-certified CAN with programmable FIFO mode, loop-back self-test, and disabled automatic retransmission for time-triggered operation.

Manufacturer

Infineon Technologies AG is a German semiconductor manufacturer specializing in power management, automotive MCUs, and security solutions, with global manufacturing and R&D infrastructure.

The CY96670 series was developed by Cypress (acquired by Infineon in 2020) to serve automotive and industrial applications demanding high-integration 16-bit control, certified CAN communication, and mixed-signal peripherals - especially where stepping motor control and LCD UI coexist on a single chip.

FAQ

What is the maximum operating frequency of the CY96F673ABPMC1-GS-UJE1 CPU?

The CPU achieves up to 32MHz operation using the on-chip PLL multiplier (×1 to ×8) driven by an external 4–8MHz ceramic resonator or crystal. This yields a minimum instruction cycle time of 31.2ns, verified in AC Characteristics section (Table 14.4) of datasheet Rev. *D.

Does the CY96F673ABPMC1-GS-UJE1 support CAN FD or only classical CAN?

This device supports only Classical CAN per ISO 11898-1:2015 (CAN 2.0A/B), with bit rates up to 1Mbps and ISO16845 physical-layer certification. It does not implement CAN FD features such as flexible data-rate or extended frame formats - confirmed in Section "CAN" of datasheet Rev. *D, page 23.

How many independent PWM channels does the stepping motor controller provide?

The integrated Stepping Motor Controller provides two independent channels (SMC0/SMC1), each with two synchronized 8/10-bit PWM outputs - totaling four PWM channels. Each channel drives a full H-bridge pair, and internal prescaling (1, 1/4, 1/5, ..., 1/16) allows fine-grained timing control for microstepping.

Is the Flash memory protected against unauthorized read-out?

Yes - the device implements Flash Security features including code protection bits that prevent external read-out of Flash contents via debug interface or serial programming. Security activation is irreversible and must be configured during programming; details are specified in Section "Flash Memory" (page 4) and "Security Function" (OCD section) of datasheet Rev. *D.
