Product details
Overview
SAK-XC167CI-16F20F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 128 KB on-chip Flash, 2 KB DPRAM, 4 KB DSRAM, and 2 KB PSRAM. It integrates TwinCAN (Rev. 2.0B), dual ASC/SSC interfaces, a 16-channel 10-bit ADC (2.55 µs conversion), CAPCOM6 PWM unit, and real-time clock with dedicated oscillator. Designed for automotive powertrain and industrial motor control systems requiring deterministic timing and CAN-based communication.
For engineers reviewing the SAK-XC167CI-16F20F BB datasheet, SAK-XC167CI-16F20F BB pinout, SAK-XC167CI-16F20F BB application in motor control or CAN gateway, or SAK-XC167CI-16F20F BB equivalent for legacy C166SV2 migration, this page delivers verified technical context, package mapping, functional alternatives, and supply-chain support specific to this RoHS-compliant 144-pin TQFP derivative.
Technical Context
The XC167CI-16F20F BB implements a 5-stage pipelined C166SV2 CPU core operating at up to 40 MHz (25 ns instruction cycle), supporting single-cycle 16×16 multiply and MAC operations. Its interrupt system delivers 77 sources across 16 priority levels with 50 ns sample rate, managed via Peripheral Event Controller (PEC) for zero-latency data transfers.
On-chip peripherals include two independent CAN nodes (TwinCAN Rev. 2.0B, 32 message objects), dual ASC/SSC serial interfaces, and a programmable GPT12E timer unit with five timers. Clock generation uses an internal PLL (1:0.15–1:10) or prescaler (1:1–60:1), enabling flexible system synchronization without external clock synthesis.

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-XC167CI-16F40F BB | Same core, Flash, RAM, and peripheral set; differs only in max CPU clock (40 MHz vs. 20 MHz) and extended temperature range (-40 °C to +125 °C for both). | Identical use cases; selected when higher instruction throughput (e.g., complex FOC math) is required without changing PCB layout. | Drop-in replacement if board-level timing margins allow 40 MHz operation; verify oscillator stability and power dissipation. |
| SAF-XC164CS-8F40F | Successor C166SV2 derivative with 64 KB Flash, reduced peripheral count (single CAN, no TwinCAN), and lower max clock (40 MHz) but same 144-TQFP footprint. | Suitable for cost-sensitive body electronics where dual CAN is unnecessary; lacks CAPCOM6 and real-time clock. | Consider for new designs targeting simplified CAN topology and lower BOM cost; not recommended for ECU or gateway upgrades. |
Compared with SAK-XC167CI-16F20F BB, the 40F variant offers higher computational headroom within identical thermal and packaging constraints, while the XC164CS sacrifices TwinCAN and CAPCOM6 to reduce silicon area - making it viable only where those features are unused.

FAQ
What is the maximum operating frequency of the SAK-XC167CI-16F20F BB?
The SAK-XC167CI-16F20F BB operates at a maximum CPU clock frequency of 20 MHz, corresponding to a 50 ns instruction cycle time. This is fixed by the "20F" suffix in the ordering code and confirmed in Table 1 of the V1.3 datasheet, which lists it alongside the 40F variant as a distinct derivative with identical feature set but halved clock capability.
Does the SAK-XC167CI-16F20F BB support in-system programming (ISP)?
Yes - the device includes an on-chip bootstrap loader that enables in-system programming of its 128 KB Flash memory via ASC0 or ASC1 serial interfaces. The bootloader resides in ROM and activates on power-up or reset when configured boot pins indicate serial download mode, eliminating need for external programmers during field updates.
Is the TwinCAN module fully compatible with ISO 11898-1:2003?
Yes - the TwinCAN module complies with ISO 11898-1:2003 (CAN Specification Version 2.0B active), supporting both Full CAN and Basic CAN modes. It provides two independent CAN controllers sharing one set of message objects, with hardware-supported message filtering, transmission prioritization, and automatic retransmission - all verified in Section 3.13 of the V1.3 datasheet.
What is the purpose of the DPRAM in the SAK-XC167CI-16F20F BB?
The 2 KB dual-port RAM (DPRAM) allows simultaneous read/write access from CPU and peripheral modules such as the Peripheral Event Controller (PEC) or CAPCOM units. This enables lock-free data exchange between real-time control tasks and background DMA transfers - critical for jitter-free PWM generation and ADC result buffering in motor control applications.
