Infineon Technologies XC874CLM16FVA5VACKXUMA1

Overview

XC874CLM16FVA5VACKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the 8051 instruction set and executing instructions in two clock cycles. It integrates 52 KB Flash, 256 B RAM, 3 KB XRAM, and a 10-bit 8-channel ADC. The device operates with 5 V I/O supply and internal 2.5 V core voltage regulation, targeting automotive body electronics and industrial control applications.

For engineers reviewing the XC874CLM16FVA5VACKXUMA1 datasheet, XC874CLM16FVA5VACKXUMA1 pinout, XC874CLM16FVA5VACKXUMA1 application, or XC874CLM16FVA5VACKXUMA1 equivalent, key selection considerations include its integrated MultiCAN interface, CORDIC coprocessor for trigonometric computation, CCU6 capture/compare unit for motor control timing, and on-chip debug support via JTAG.

Technical Context

The XC874CLM16FVA5VACKXUMA1 implements a two-clock-per-machine-cycle 8051-compatible CPU core with dual data pointers and hardware multiplication/division (MDU) plus CORDIC acceleration for real-time angle and magnitude calculations. Its memory architecture includes segmented Flash (52 KB), protected Boot ROM (8 KB), and separate XRAM (3 KB) accessible via MOVX instructions.

Peripheral integration centers on deterministic real-time control: MultiCAN v2.0B supports up to 16 message objects; CCU6 provides six PWM channels with dead-time insertion; Timer 21 enables high-resolution position capture; and the 10-bit ADC features configurable conversion sequences with hardware trigger synchronization to timers or CAN events.

FAQ

Does XC874CLM16FVA5VACKXUMA1 support CAN FD?

No. This device implements MultiCAN v2.0B, which supports Classical CAN only (up to 1 Mbps). It lacks the arbitration bit rate switching, flexible data-length, and CRC enhancements required for CAN FD. For CAN FD applications, consider Infineon's XMC4000 or AURIX TC2xx families.

What is the maximum ADC sampling rate achievable?

The 10-bit ADC achieves a minimum conversion time of 1.5 µs per sample, enabling up to 667 kSPS in burst mode with hardware triggers. However, practical throughput is limited by channel sequencing and result readout; typical continuous sampling across all 8 channels yields ~100 kSPS with timer-synchronized acquisition.

Is the CORDIC unit accessible via standard 8051 instructions?

No. The CORDIC coprocessor is accessed exclusively through dedicated SFR registers (CORDICxH/CORDICxL) and requires explicit initialization of operation mode, operand sign, and iteration count. It operates asynchronously and signals completion via interrupt flag CORDICIF in the IRCON register.

Can the embedded voltage regulator be bypassed for external core supply?

No. The internal 2.5 V regulator is fixed and non-bypassable; VDDCORE is not exposed externally. The device requires only a single 5 V supply on VDDIO, with internal regulation delivering stable 2.5 V to the core logic - this architecture prevents misconfiguration and ensures AEC-Q100 compliance.
