Product details

Overview

SAF-XC164CS-16F20F BB from Infineon Technologies is a 16-bit C166 family microcontroller with 256 KB on-chip Flash, 16 KB RAM, and integrated CAN 2.0B controller. It operates at 20 MHz, supports JTAG debugging, and targets automotive body electronics and industrial motor control systems.

For engineers reviewing the SAF-XC164CS-16F20F BB datasheet, SAF-XC164CS-16F20F BB pinout, SAF-XC164CS-16F20F BB application, or SAF-XC164CS-16F20F BB equivalent, key selection criteria include Flash endurance (10k write/erase cycles), CAN bus timing compliance, real-time interrupt latency (<1 µs), and qualification per AEC-Q100 Grade 2.

Technical Context

This MCU implements the C166S V2 core with 5-stage pipeline and supports deterministic interrupt handling via priority-based vector table. It integrates a 10-bit ADC with 8 channels, 3 capture/compare units for PWM generation, and a watchdog timer with windowed mode.

The on-chip CAN controller supports bit rates up to 1 Mbps, message objects with hardware acceptance filtering, and automatic retransmission. Power management includes idle, sleep, and power-down modes with wake-up via CAN, GPIO, or timer events.

FAQ

Is SAF-XC164CS-16F20F BB pin-compatible with other XC164 variants?

No. SAF-XC164CS-16F20F BB uses a 64-pin LQFP package with specific pin assignments for CAN, ADC, and memory interface. Pinouts differ from XC164S and XC164CM variants due to differing peripheral sets and signal multiplexing-migration requires PCB redesign and firmware adaptation.

Does this MCU support bootloading over CAN?

Yes. The SAF-XC164CS-16F20F BB includes a ROM-based bootloader accessible via CAN using standardized UDS services (0x31, 0x34, 0x36, 0x37). Bootloader activation requires specific CAN ID sequence and checksum validation per Infineon Application Note AP20012.

What is the maximum operating frequency of the internal oscillator?

The SAF-XC164CS-16F20F BB does not include an internal RC oscillator. It requires an external crystal (1–20 MHz) or clock source connected to XTAL1/XTAL2. System clock is derived directly from this source or multiplied via PLL (if enabled in configuration registers).

Can the on-chip Flash be programmed in-circuit?

Yes. In-system programming (ISP) is supported via JTAG or CAN using Infineon's DAS software tools. Flash sectors can be erased and rewritten while the device remains soldered on the target board, enabling field firmware updates without removing the MCU.
