Infineon Technologies CY96F675RBPMC1-GS-UJE2

Overview

CY96F675RBPMC1-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with integrated CAN 2.0A/B controller, 128.5KB+32KB Flash, 4KB RAM, and 48–50 general-purpose I/Os in LQFP-64 package. It features an on-chip PLL enabling up to 32MHz CPU operation from a 4–8MHz external resonator, 8/10-bit SAR ADC with 12 channels, dual-operation Flash for concurrent read/program, and hardware watchdog with window function. Used in automotive body control modules requiring real-time CAN communication and motor control.

For engineers reviewing the CY96F675RBPMC1-GS-UJE2 datasheet, CY96F675RBPMC1-GS-UJE2 pinout, CY96F675RBPMC1-GS-UJE2 application, or CY96F675RBPMC1-GS-UJE2 equivalent, key selection criteria include CAN 1Mbps compliance (ISO16845), 32MHz max CPU frequency with 31.2ns instruction cycle, dual-bank Flash security, stepping motor controller with two synchronized 8/10-bit PWMs per channel, and low-power operation across 13 configurable modes.

Technical Context

The CY96F675RBPMC1-GS-UJE2 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 system supports independent domain selection-CPU, peripheral bus 1, and peripheral bus 2-each assignable to main oscillator (4–8MHz), subclock (32.768kHz), or internal RC (100kHz/2MHz).

Peripheral integration includes a dedicated stepping motor controller with four high-current outputs per channel, LCD controller supporting 4COM × 24SEG, and a sound generator mixing 8-bit PWM with 16-bit tone counter. The on-chip debugger uses one-wire interface with 6 hardware breakpoints and 42-branch trace capability, enabling non-intrusive development in resource-constrained automotive ECUs.

FAQ

What is the maximum operating temperature range for CY96F675RBPMC1-GS-UJE2?

The CY96F675RBPMC1-GS-UJE2 is qualified for automotive-grade operation from −40°C to +125°C ambient temperature, with full electrical specifications guaranteed across this range. Its on-chip voltage regulator and thermal protection circuitry ensure stable performance under under-hood thermal stress conditions typical in body control modules.

Does CY96F675RBPMC1-GS-UJE2 support JTAG debugging?

No-CY96F675RBPMC1-GS-UJE2 uses a proprietary one-wire on-chip debugger (OCD) interface, not JTAG. Debug access requires Infineon's CY8CKIT-002 or compatible OCD probe, supporting hardware breakpoints, trace, and real-time execution profiling without consuming additional pins or bandwidth.

Can the internal RC oscillator be used as the main system clock source?

Yes-the internal 100 kHz or 2 MHz RC oscillator can serve as the main clock source, enabling fast wake-up from stop modes (<10 µs). However, it lacks the accuracy required for CAN bit timing or RTC calibration; use only for non-timing-critical initialization or low-power background tasks.

How is flash memory security implemented on this MCU?

Flash security is enforced via a dedicated Flash Security feature that disables external read-out of program memory through the serial programming interface. Once enabled, it prevents unauthorized access to firmware content-even during debug sessions-unless a full chip erase is performed, which also clears all protected data.
