Product details
Overview
SAF-XC164N-8F40F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 64 KB on-chip Flash, 6 KB total SRAM (2 KB DPRAM + 2 KB DSRAM + 2 KB PSRAM), 40 MHz CPU clock (25 ns instruction cycle), and integrated CAN 2.0B controller licensed from Robert Bosch GmbH. It targets real-time motor control and industrial automation systems requiring deterministic interrupt response down to 50 ns.
For engineers reviewing the SAF-XC164N-8F40F BB datasheet, SAF-XC164N-8F40F BB pinout, SAF-XC164N-8F40F BB application, or SAF-XC164N-8F40F BB equivalent, key selection criteria include its 100-pin TQFP package, dual 16-channel CAPCOM units, GPT12E timer, on-chip PLL with 1:0.15–1:10 multiplication, and JTAG-based OCDS debug support.
Technical Context
The XC164N implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and 21-cycle 32/16 divide. Its memory subsystem supports 16 Mbytes linear addressing, with on-chip SRAM partitioned into dual-port (DPRAM), data (DSRAM), and program/data (PSRAM) banks for concurrent access.
Peripheral integration includes two ASCs (asynchronous/synchronous serial), two SSCs (high-speed synchronous serial), CAPCOM6 for flexible PWM generation, and a real-time clock. Clock generation uses either an internal PLL or prescaler, enabling precise timing control across industrial operating conditions (−40°C to +85°C).
Key Specifications

| GPT12E Timer | 5-timer unit with programmable prescaler, reload registers, and event capture - supports encoder position tracking and time-stamped fault logging |
| On-Chip Debug Support (OCDS) | JTAG interface with full breakpoint, watchpoint, and trace capabilities - enables non-intrusive real-time debugging without halting CPU execution |
| Power Management Modes | Idle, Sleep, and Power Down with wake-up via external interrupt or RTC alarm - reduces active current to <100 µA in low-power monitoring applications |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|

IC Role / Device Role / Timing Role: CAN 2.0B node managing message arbitration, filtering, and error handling while executing LIN gateway logic via ASC1. Use Value: Integrated CAN controller eliminates external transceiver dependency and reduces BOM count by one IC in cost-sensitive body electronics. |
| Programmable Logic Controllers (PLCs) | Industrial Sensor Fusion Gateways |
Use Scenario: Modular I/O processing unit in DIN-rail mounted PLCs handling discrete inputs, analog conditioning, and fieldbus communication. IC Role / Device Role / Timing Role: Dual ASC interfaces manage Modbus RTU over RS-485, while PEC offloads serial data movement from CPU during scan cycles.

IC Role / Device Role / Timing Role: Real-time clock maintains time-stamped sensor logs; GPT12E triggers periodic ADC conversions independent of main loop timing. Use Value: On-chip 6 KB SRAM buffers 12+ seconds of 1 kHz sensor streams, eliminating need for external FIFO memory in compact gateway designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAF-XC164CS-8F40F | Same C166SV2 core and 64 KB Flash, but lacks CAPCOM6 unit and has reduced peripheral set (no SSC, only one ASC) | Suitable for simpler motor control without complex PWM or high-speed serial bridging | Select when CAPCOM6 and dual SSC are not required to reduce software complexity and cost |
| SAF-XC167CI-16F40F | Enhanced C166SV2 derivative with 128 KB Flash, 16 KB SRAM, and additional CAPCOM units; pin-compatible but larger memory map | Required for applications needing larger firmware images or extended real-time data logging buffers | Choose when future firmware expansion or advanced diagnostics demand >64 KB code space and >6 KB RAM |
Compared with SAF-XC164CS-8F40F, the SAF-XC164N-8F40F BB delivers full CAPCOM6 PWM flexibility and dual SSC for sensor data aggregation; versus SAF-XC167CI-16F40F, it offers identical real-time performance at lower memory cost-ideal for volume production where 64 KB Flash suffices.
