Product details
Overview
XC161CS32F40FBBAFXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 CPU core, featuring 256 KB on-chip Flash, 12 KB total SRAM (2 KB DPRAM + 4 KB DSRAM + 6 KB PSRAM), and integrated TwinCAN 2.0B interface with 32 message objects across two CAN nodes. It operates at up to 40 MHz CPU clock (25 ns instruction cycle), supports 10-bit/8-bit A/D conversion in as little as 2.15 µs, and targets automotive powertrain and industrial motor control systems requiring deterministic real-time response.
For engineers reviewing the XC161CS32F40FBBAFXUMA1 datasheet, XC161CS32F40FBBAFXUMA1 pinout, XC161CS32F40FBBAFXUMA1 application, or XC161CS32F40FBBAFXUMA1 equivalent, key selection criteria include its 144-pin TQFP RoHS-compliant package, 16-priority-level interrupt system with 73 sources, on-chip JTAG-based OCDS debug support, and dual ASC/SSC serial interfaces for sensor and actuator communication.
Technical Context
The XC161CS32F40FBBAFXUMA1 implements a 5-stage pipelined C166SV2 core with zero-cycle jumps, 1-cycle 16×16 multiply, and 21-cycle 32/16 divide-enabling tight control loops in motor drive firmware. Its memory subsystem includes separate dual-port RAM for concurrent CPU/peripheral access and 256 KB Flash with configurable wait states (WSFLASH register) for reliable execution at 40 MHz.
Peripheral integration centers on real-time I/O coordination: the GPT12E timer unit provides five independent timers with capture/compare capability; CAPCOM1/2 units deliver 32 dedicated I/O pins for PWM generation and edge detection; and the TwinCAN module supports full CAN protocol with gateway functionality between two independent CAN networks.
