Infineon Technologies SAF-XC824MT-1FGIAA

Overview

SAF-XC824MT-1FGIAA 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 Flash memory, 256 bytes RAM, 256 bytes XRAM, a 10-bit 4-channel ADC with differential input support, and three 16-bit timers (T0/T1/T2), targeting embedded control in automotive body electronics and industrial sensor interfaces.

For engineers reviewing the SAF-XC824MT-1FGIAA datasheet, SAF-XC824MT-1FGIAA pinout, SAF-XC824MT-1FGIAA application, or SAF-XC824MT-1FGIAA equivalent, key selection criteria include its 48 MHz on-chip oscillator, independent watchdog timer with programmable window, LED/touch-sense controller (LEDTSCU), and PG-TSSOP-16 package with -40 °C to +85 °C operating range.

Technical Context

The XC824 implements a two-clock-per-cycle 8051-compatible core with dual data pointers and on-chip voltage regulation delivering 2.5 V core supply from a 2.5–5.5 V I/O rail. Its peripheral set includes a synchronous serial channel (SSC) supporting master/slave modes, UART with full/half-duplex operation, and I²C interface-all sharing dedicated hardware resources without CPU intervention during transfer.

Power management is implemented via idle and power-down modes, with wake-up capability from RTC interrupt or external pin event. The 16-bit CCU6 unit provides PWM generation with dead-time insertion, while the MDU enables integer multiplication/division in hardware-critical for real-time motor control loop calculations.

FAQ

Does SAF-XC824MT-1FGIAA support in-system programming via the DAP pin?

Yes. The single-pin Debug Access Port (DAP) supports both on-chip debugging and in-system programming using Infineon's SPD protocol. This enables firmware updates and real-time variable inspection without requiring additional JTAG pins or external debug hardware-ideal for space-constrained designs where board area is limited.

What is the maximum sampling rate of the 10-bit ADC in SAF-XC824MT-1FGIAA?

The ADC achieves up to 100 kSPS (kilo-samples per second) in single-conversion mode with internal clock derived from the 48 MHz oscillator. When using digital filtering for enhanced resolution (up to 13-bit effective), the sample rate reduces to approximately 10 kSPS due to oversampling and decimation overhead.

Can the CCU6 unit generate complementary PWM outputs with programmable dead time?

Yes. The 16-bit Capture/Compare Unit (CCU6) supports complementary PWM channel pairs with hardware-configurable dead-time insertion ranging from 1 to 255 clock cycles. This feature is essential for driving half-bridge or three-phase inverter stages without shoot-through risk.

Is the on-chip 48 MHz oscillator factory-trimmed for accuracy?

Yes. The internal RC oscillator is factory-trimmed to ±2% accuracy across the full -40 °C to +85 °C temperature range and 2.5–5.5 V supply. Calibration data is stored in the chip identification area and accessible via the JTAG ID register for runtime compensation if higher precision is required.
