Infineon Technologies CY96F683ABPMC-GS-UJE1

Overview

CY96F683ABPMC-GS-UJE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with integrated CAN 2.0A/B interface, 128.5KB Flash + 32KB RAM, 14-channel 8/10-bit SAR ADC, and dual-clock domain operation. It features an on-chip PLL enabling up to 32MHz CPU frequency from a 4–8MHz resonator, 63 I/O pins in dual-clock mode, and hardware watchdog with window function - deployed in automotive body control modules requiring deterministic real-time CAN messaging and motor actuation.

For engineers reviewing the CY96F683ABPMC-GS-UJE1 datasheet, CY96F683ABPMC-GS-UJE1 pinout, CY96F683ABPMC-GS-UJE1 application, or CY96F683ABPMC-GS-UJE1 equivalent, key selection criteria include CAN bit-rate support up to 1 Mbps, 32-message object FIFO, programmable loop-back mode for validation, and dual-operation Flash enabling concurrent code execution and firmware update.

Technical Context

The CY96F683ABPMC-GS-UJE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes - enabling efficient controller firmware migration from legacy F2MC-16LX devices. Its clock tree supports independent CPU and peripheral domain sourcing from main oscillator (4–8MHz), subclock (32.768kHz), or internal RC (100kHz/2MHz).

Peripheral integration includes a dedicated Stepping Motor Controller with two synchronized 8/10-bit PWM channels per SMC unit, high-current output drivers, and internal prescaling options (1, 1/4, 1/5, ..., 1/16). The CAN module is ISO16845 certified, supports disabled automatic retransmission for time-triggered operation, and provides maskable interrupts per message object.

FAQ

What is the maximum operating temperature range for CY96F683ABPMC-GS-UJE1?

The CY96F683ABPMC-GS-UJE1 is rated for operation from −40 °C to +105 °C ambient temperature, validated per Infineon's recommended operating conditions (Document 002-04705 Rev. *D, Section 14.2). This extends beyond standard industrial grade to meet AEC-Q100 Grade 2 requirements for under-hood automotive use.

Does CY96F683ABPMC-GS-UJE1 support CAN FD?

No. The CY96F683ABPMC-GS-UJE1 implements CAN 2.0A/B protocol only, with bit rates up to 1 Mbps. It does not support CAN FD features such as flexible data-length or higher bit rates. ISO16845 certification applies exclusively to classical CAN 2.0 conformance testing.

Can the on-chip voltage regulator be bypassed for external core supply?

No. The internal voltage regulator is fixed-function and non-bypassable; it generates the core voltage (Vcore ≈ 1.8 V) from the DVcc supply (2.7–5.5 V). External core supply is not supported - DVcc must remain within specified operating range to ensure regulator stability and flash programming integrity.

Is the Boot ROM reprogrammable or field-upgradable?

The Boot ROM is mask-programmed during fabrication and cannot be modified in the field. It contains immutable startup code, clock initialization routines, and secure serial programming interface handlers. Firmware updates occur only in user Flash memory; Boot ROM remains unchanged across all device revisions and lifecycles.
