Infineon Technologies XC8662FRIBEKXUMA1

Overview

XC8662FRIBEKXUMA1 from Infineon Technologies is an 8-bit single-chip microcontroller based on the XC800 core, compatible with the standard 8051 instruction set and executing instructions at two clocks per machine cycle. It integrates 4 Kbytes of Flash program memory, 256 bytes of RAM, 512 bytes of XRAM, and an 8-channel 10-bit ADC. It operates with a 5.0 V I/O supply and internal 2.5 V core logic supply, targeting motor control and industrial embedded systems.

For engineers reviewing the XC8662FRIBEKXUMA1 datasheet, XC8662FRIBEKXUMA1 pinout, XC8662FRIBEKXUMA1 application, or XC8662FRIBEKXUMA1 equivalent, key selection factors include its 16-bit CCU6 capture/compare unit for PWM generation, UART/SSC serial interfaces, watchdog timer with programmable timeout, and PG-TSSOP-38 package compatibility with automotive-grade thermal range (–40 °C to 125 °C).

Technical Context

The XC8662FRIBEKXUMA1 implements a two-clock-per-cycle 8051-compatible core with dual data pointers and on-chip voltage regulation generating 2.5 V for core logic from a 5.0 V I/O rail. Its memory architecture includes 4 Kbytes of P-Flash (program), 4 Kbytes of D-Flash (data), and protected Boot ROM containing monitor firmware for on-chip debug.

It features three independent 16-bit timers (T0/T1/T2), a dedicated CCU6 module supporting center-aligned and edge-aligned PWM with dead-time insertion, and a 10-bit SAR ADC with 8 input channels and configurable sampling rate up to 100 kSPS - all synchronized to the same clock domain for deterministic timing in real-time control loops.

Key Specifications

Pinout & Package

XC8662FRIBEKXUMA1 is housed in a 38-pin PG-TSSOP (Plastic Thin Shrink Small Outline Package) with exposed thermal pad, optimized for thermal dissipation in motor control applications. Pin functions are defined per the XC866 family datasheet Rev. V1.2 (2007), with dedicated pins for CCU6 outputs, ADC inputs, UART/SSC signals, and reset/watchdog control.

FAQ

What is the maximum operating frequency of the XC8662FRIBEKXUMA1 core?

The XC8662FRIBEKXUMA1 core runs at up to 26.67 MHz when driven by the internal PLL with a 13.33 MHz crystal input. The two-clock-per-cycle architecture delivers effective throughput equivalent to a 13.33 MHz standard 8051, enabling deterministic execution of motor control loops within 75 µs per cycle.

Does XC8662FRIBEKXUMA1 support in-application programming (IAP) of Flash memory?

Yes - the device supports IAP via its D-Flash sector, allowing firmware updates without halting real-time control. The memory protection scheme permits selective locking of P-Flash pages while leaving D-Flash accessible for data logging or parameter storage during runtime.

Can the 10-bit ADC operate synchronously with the CCU6 PWM timer?

Yes - the ADC can be triggered directly by CCU6 events (e.g., PWM center point or edge), ensuring sample alignment with motor phase current peaks. This hardware synchronization eliminates software-induced jitter and enables consistent current reconstruction for field-oriented control.

Is the PG-TSSOP-38 package of XC8662FRIBEKXUMA1 RoHS-compliant?

Yes - the XC8662FRIBEKXUMA1 uses lead-free (Pb-free) packaging and complies with EU RoHS Directive 2011/65/EU. The PG-TSSOP-38 package meets JEDEC standards for moisture sensitivity level (MSL) 3 and is qualified for standard reflow profiles including J-STD-020.
