Product details
Overview
XC167CI32F40FBBAKXUMA1 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 1-cycle MAC and 1-cycle 16×16 multiplication, and targets real-time embedded control in automotive powertrain and industrial motor drives.
For engineers reviewing the XC167CI32F40FBBAKXUMA1 datasheet, XC167CI32F40FBBAKXUMA1 pinout, XC167CI32F40FBBAKXUMA1 application, or XC167CI32F40FBBAKXUMA1 equivalent, key selection criteria include its 144-pin TQFP package with RoHS-compliant green finish, 16-priority-level interrupt system with 77 sources, 16-channel 10-bit ADC (2.55 µs conversion), and dual ASC/SSC serial interfaces for sensor and actuator communication.
Technical Context
The XC167CI32F40FBBAKXUMA1 implements a 5-stage pipelined C166SV2 CPU core with zero-cycle jumps, register-based architecture, and two local register banks for fast context switching. Its memory subsystem includes linear 16 MB address space, on-chip boot loader, and configurable wait-state control for Flash access timing.
Peripheral integration centers on deterministic real-time control: CAPCOM1/2 provide 32 I/O pins for capture/compare functions; CAPCOM6 delivers flexible PWM generation with 3/6 capture/compare channels; GPT12E offers five timers; and TwinCAN enables concurrent CAN bus arbitration with gateway functionality between two independent nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive-grade microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC2786X-104F | Enhanced C2000-compatible core, 1 MB Flash, 128 KB RAM, but no TwinCAN - uses single CAN 2.0B with 16 objects. | Lacks dual-CAN gateway capability; requires external CAN controller for multi-bus systems. | Select when higher code density and larger RAM are needed, and CAN gateway is handled externally or not required. |
| SPC560P50L5 | Power Architecture e200z0 core, 512 KB Flash, 48 KB RAM, dual CAN 2.0B with 64 message objects, but no integrated ASC/SSC/IIC combo. | Superior CAN scalability but lacks native UART/SPI/I2C concurrency; requires external transceivers for non-CAN serial links. | Select for CAN-heavy applications where ASC/SSC/IIC are replaced by external bridges or omitted entirely. |
Compared with SAK-XC2786X-104F and SPC560P50L5, XC167CI32F40FBBAKXUMA1 uniquely balances mature 16-bit deterministic performance, integrated multi-serial connectivity, and hardware TwinCAN gateway - making it optimal for cost-sensitive, thermally demanding ECU designs requiring no external protocol translators.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The XC167CI32F40FBBAKXUMA1 achieves a maximum CPU clock of 40 MHz, delivering a 25 ns instruction cycle time for single-cycle execution of most instructions. This timing assumes proper Flash wait-state configuration (via WSFLASH in IMBCTRL) and stable 3.3 V supply within specification limits.
Does this microcontroller support in-application programming (IAP) of Flash memory?
Yes - the device supports in-system programming (ISP) and in-application programming (IAP) of its 256 KB on-chip Flash via the on-chip bootstrap loader and JTAG interface. Verified Flash endurance is 10,000 write/erase cycles with 20-year data retention at 125°C per Section 5.2 of the datasheet.
How many CAN message objects does the TwinCAN module support, and are they shared between CAN0 and CAN1?
The TwinCAN module provides 32 dedicated message objects - 16 allocated to CAN0 and 16 to CAN1 - with independent filtering, transmission, and reception logic. Hardware gateway functionality enables direct message forwarding between buses without CPU intervention or RAM buffering.
Is the 144-pin TQFP package lead-free and RoHS-compliant?
Yes - the XC167CI32F40FBBAKXUMA1 uses a "Green TQFP" package explicitly designated as RoHS-compliant in Table 1 and Section 5.1 of the datasheet (V1.1, 2006-08), with lead-free terminations and halogen-free molding compound.
