Product details

Overview

XC167CI16F40FBBFXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 128 KB on-chip Flash, 8 KB total SRAM (2 KB DPRAM + 4 KB DSRAM + 2 KB PSRAM), and integrated TwinCAN 2.0B interface with 32 message objects across two CAN nodes. It operates at 40 MHz CPU clock (25 ns instruction cycle), supports 16-priority-level interrupts with 77 sources, and targets real-time embedded control in automotive powertrain and industrial motor drives.

For engineers reviewing the XC167CI16F40FBBFXUMA1 datasheet, XC167CI16F40FBBFXUMA1 pinout, XC167CI16F40FBBFXUMA1 application, or XC167CI16F40FBBFXUMA1 equivalent, key selection criteria include its 144-pin TQFP RoHS-compliant package, dual ASC/SSC serial interfaces, 16-channel 10-bit ADC with 2.55 µs conversion time, and on-chip JTAG-based OCDS debug support.

Technical Context

The XC167CI16F40FBBFXUMA1 implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and MAC instructions-enabling deterministic real-time execution in safety-critical control loops. Its memory subsystem includes 128 KB Flash with EEPROM emulation capability, three SRAM blocks mapped to distinct address spaces for code/data separation, and a 1024-byte SFR area compatible with the C166 family.

Peripheral integration centers on deterministic timing: the GPT12E timer unit provides five independent timers with capture/compare and PWM generation; CAPCOM6 delivers flexible 3/6-channel PWM with dead-time insertion; and the TwinCAN module supports concurrent full-CAN operation on two independent nodes with hardware message filtering and gateway functionality between CAN buses.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SAK-XC2786X-104F	Enhanced C2000-compatible core, 144 MHz max, 512 KB Flash, no TwinCAN - uses single CAN 2.0B + LIN.	Targets higher-performance motor control requiring >100 MIPS; lacks dual-CAN gateway capability.	Select when migrating to scalable Infineon XC2000 family with larger memory and DSP extensions, but requires CAN gateway redesign.
SPC560P50L5	Power Architecture e200z0 core, 64 MHz, 512 KB Flash, dual CAN 2.0B + FlexRay, AEC-Q100 Grade 1.	Designed for automotive powertrain with ASIL-B functional safety support; includes hardware CRC and memory protection units.	Choose for new designs requiring ISO 26262 compliance where XC167CI lacks certified safety mechanisms.

Compared with SAK-XC2786X-104F and SPC560P50L5, the XC167CI16F40FBBFXUMA1 delivers deterministic real-time performance at lower clock speed with proven dual-CAN gateway functionality and mature toolchain support, making it optimal for cost-sensitive, non-ASIL automotive and industrial control where legacy C166 ecosystem compatibility is required.

FAQ

What is the maximum operating temperature range for XC167CI16F40FBBFXUMA1?

The XC167CI16F40FBBFXUMA1 is rated for operation from –40 °C to +125 °C ambient temperature, validated per Infineon's industrial qualification standards and supported by thermal resistance values R_ΘJC = 12.5 K/W and R_ΘJL = 25.0 K/W specified in the 2006 datasheet revision V1.3.

Does XC167CI16F40FBBFXUMA1 support in-system programming (ISP) via its on-chip bootloader?

Yes-the device includes a ROM-resident bootstrap loader accessible via ASC0 UART interface, enabling field firmware updates without external programming hardware; it supports standard Intel HEX format and requires only a 3.3 V logic-level serial connection with baud rates up to 115.2 kbps.

Can the 16-channel ADC operate simultaneously with the TwinCAN modules without CPU intervention?

Yes-ADC conversions can trigger PEC channel transfers directly into SRAM buffers while TwinCAN message objects are processed autonomously; this concurrent operation is enabled by separate clock domains and hardware handshaking, confirmed in Section 3.10 and 3.13 of the datasheet.

Is JTAG debug support fully compliant with IEEE 1149.1, and what debug features are implemented?

Yes-the device implements full IEEE 1149.1 JTAG boundary-scan and on-chip debug support (OCDS), including hardware breakpoints, data watchpoints, real-time trace via debug port, and register visibility during halted or run-time states, as detailed in Section 3.5 of the V1.3 datasheet.
