Infineon Technologies XC167CI32F40FBBAKXQMA1

Overview

XC167CI32F40FBBAKXQMA1 from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 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 103 GPIOs, and targets automotive powertrain and industrial motor control applications requiring real-time deterministic response.

For engineers reviewing the XC167CI32F40FBBAKXQMA1 datasheet, XC167CI32F40FBBAKXQMA1 pinout, XC167CI32F40FBBAKXQMA1 application, or XC167CI32F40FBBAKXQMA1 equivalent, key selection considerations include its 16-priority-level interrupt system with 77 sources, 8-channel Peripheral Event Controller (PEC) for single-cycle data transfers, on-chip real-time clock with dedicated oscillator, and RoHS-compliant 144-pin TQFP package with 0.5 mm pitch.

Technical Context

The XC167CI32F40FBBAKXQMA1 implements a 5-stage pipelined C166SV2 CPU core with zero-cycle jumps, 1-cycle 16×16 multiplication, and MAC instructions-enabling deterministic execution in time-critical control loops. Its memory subsystem includes separate dual-port RAM for concurrent CPU/peripheral access and programmable external bus controller supporting up to 12 MB address space with five chip-selects and hold/acknowledge arbitration.

Peripheral integration centers on real-time I/O management: twin 16-channel CAPCOM units support flexible PWM generation and capture timing down to 50 ns sample rate; the GPT12E timer unit provides five independent timers; and the TwinCAN module delivers full CAN 2.0B compliance with gateway functionality between two independent CAN networks.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time for XC167CI32F40FBBAKXQMA1?

The device operates at a maximum CPU clock frequency of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing assumes proper configuration of the on-chip PLL and Flash wait states (WSFLASH bits in IMBCTRL register) to match the selected CPU frequency and Flash access speed grade.

Does XC167CI32F40FBBAKXQMA1 support CAN FD or only classical CAN 2.0B?

XC167CI32F40FBBAKXQMA1 supports only Classical CAN 2.0B (up to 1 Mbit/s) via its TwinCAN module. It does not implement CAN FD features such as flexible data-rate or extended data length. The module provides full 2.0B compliance with 32 message objects per node and hardware gateway functionality between CAN0 and CAN1.

How is the 12 KB on-chip RAM organized, and what are the access characteristics of each segment?

The 12 KB RAM consists of 2 KB dual-port RAM (DPRAM) accessible simultaneously by CPU and peripherals, 4 KB data SRAM (DSRAM) optimized for variable storage, and 6 KB program/data SRAM (PSRAM) usable for both code and data. DPRAM supports concurrent read/write from different masters without arbitration delay, critical for real-time buffer sharing in motor control loops.

Is the XC167CI32F40FBBAKXQMA1 RoHS compliant, and what package variant does the 'FBBAK' suffix indicate?

Yes, XC167CI32F40FBBAKXQMA1 is RoHS compliant and uses a green (halogen-free) 144-pin TQFP package. The 'FBBAK' suffix denotes Infineon's standard 144-pin TQFP with 0.5 mm pitch, exposed pad for thermal enhancement, and industrial-grade marking (XQMA1 indicates qualification level and date code).
