Infineon Technologies XC8662FRABEKXUMA1

Overview

XC8662FRABEKXUMA1 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 KB of flash program memory, 256 bytes of RAM, 512 bytes of XRAM, and an 8-channel 10-bit ADC. It operates at 5.0 V supply with industrial temperature range (–40 to +85 °C) and is packaged in PG-TSSOP-38 for motor control and power conversion applications.

For engineers reviewing the XC8662FRABEKXUMA1 datasheet, XC8662FRABEKXUMA1 pinout, XC8662FRABEKXUMA1 application, or XC8662FRABEKXUMA1 equivalent, this page provides verified functional identity, validated package mapping, confirmed peripheral register access types (e.g., rwh for Px_DIR), Flash memory protection scheme details, and real-world timing roles in PWM generation and LIN-capable embedded systems.

Technical Context

The XC8662FRABEKXUMA1 implements a two-clock-per-cycle 8051-compatible core with dual data pointers and on-chip voltage regulation generating 2.5 V core logic supply from 5.0 V I/O supply. Its CCU6 capture/compare unit supports 16-bit PWM with dead-time insertion, while the UART and SSC interfaces enable serial communication in resource-constrained embedded nodes.

Reset architecture includes power-on, hardware, brownout (for 2.5 V core), watchdog, and power-down wake-up via RXD or EXINT0. Clock generation uses an on-chip oscillator with PLL and loss-of-lock detection, supporting precise timing in closed-loop motor control where jitter-sensitive PWM alignment is required.

FAQ

Does XC8662FRABEKXUMA1 support LIN physical layer directly?

No, XC8662FRABEKXUMA1 does not integrate a LIN transceiver. It implements the LIN protocol stack in firmware and requires an external LIN transceiver (e.g., TLE7259) connected to its UART pins. The device includes a LIN bootloader (BSL) in Boot ROM for firmware updates over the LIN network.

What is the maximum ADC sampling rate for XC8662FRABEKXUMA1?

The ADC achieves up to 100 kSPS maximum sampling rate with internal clock derived from system clock divided by 4. Conversion time is 13.5 µs per 10-bit sample, and channel scanning supports automatic sequencing across all 8 inputs without CPU intervention.

Can the CCU6 module generate complementary PWM signals with dead time?

Yes, the CCU6 module supports complementary PWM output on paired channels (e.g., CC60/CC61) with programmable dead-time insertion ranging from 0 to 1023 clock cycles. Dead time is applied symmetrically and configurable per channel pair via CCU6 register settings.

Is the 256-byte RAM mirrored or banked?

The 256-byte RAM is linearly addressed and not banked or mirrored. It occupies addresses 0x00–0xFF in the internal data space and supports direct and indirect addressing modes. Special function registers (SFRs) reside separately in the 0x80–0xFF address range and do not overlap with RAM.
