Product details
Overview
SAF-XC167CI-16F20F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, operating at up to 20 MHz CPU clock (50 ns instruction cycle), 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 targets real-time industrial motor control and automotive body electronics.
For engineers reviewing the SAF-XC167CI-16F20F BB datasheet, SAF-XC167CI-16F20F BB pinout, SAF-XC167CI-16F20F BB application, or SAF-XC167CI-16F20F BB equivalent, key selection criteria include its 144-pin TQFP package, -40 °C to +85 °C industrial temperature grade, dual ASC/SSC serial interfaces, 16-channel 10-bit ADC with 2.55 µs conversion time, and JTAG-based on-chip debug support (OCDS).
Technical Context
The XC167CI-16F20F BB implements a 5-stage pipelined C166SV2 CPU core with zero-cycle jumps, 1-cycle 16×16 multiplication, and MAC instructions-enabling deterministic real-time execution in motor control loops. Its memory subsystem includes separate 2 KB dual-port RAM for concurrent CPU/peripheral access and 128 KB Flash with sector protection and in-system programmability.
Peripheral integration centers on deterministic timing: the GPT12E timer unit provides five independent timers with capture/compare capability; CAPCOM6 delivers flexible PWM generation with dead-time insertion; and the TwinCAN module supports full CAN protocol handling-including message filtering, transmission scheduling, and gateway functionality between CAN0 and CAN1.

Pinout & Package
SAF-XC167CI-16F20F BB is housed in a 144-pin Green TQFP package (RoHS-compliant), 20 × 20 mm body, 0.5 mm pitch, with exposed thermal pad. Pin functions are defined per Infineon's V1.3 datasheet (Aug. 2006), including dedicated XTAL1/XTAL3 oscillator inputs tied to VDDI power domain, TRST for JTAG boundary scan, and dual CANH/CANL differential pairs routed to pins P4.0–P4.3 and P5.0–P5.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTAL1 / XTAL3 | Oscillator input / output | Crystal connection points for main system clock; belong to VDDI domain-require dedicated 3.3 V supply decoupling. |
| P0.0–P0.15 | Port 0 bidirectional I/O | 16-bit general-purpose port with configurable pull-up, hysteresis, and alternate functions (e.g., address bus A0–A15 in external memory mode). |

| TRST | JTAG test reset | Asynchronous active-low reset for boundary-scan logic; required for OCDS debug initialization and flash programming. |
| VDDI | Internal regulator input | 3.3 V supply pin feeding internal voltage regulator-must be decoupled locally to ensure stable core and analog reference operation. |
Key Features
| Feature | Design Value |
|---|---|
| On-Chip Debug Support (OCDS) | JTAG interface with real-time trace, breakpoint, and watchpoint capability-enables non-intrusive debugging without code instrumentation. |
| Peripheral Event Controller (PEC) | 8-channel DMA-like engine with 24-bit addressing; transfers data between peripherals and memory in single-cycle bursts, offloading CPU during ADC or CAN buffer operations. |
| CAPCOM6 PWM Unit | 3/6-channel capture/compare unit with programmable dead-time insertion and complementary output-supports three-phase motor gate drive without external logic. |
| Real-Time Clock (RTC) | Dedicated 32.768 kHz oscillator input and calendar counter with alarm interrupt-operates independently during sleep/idle modes for time-stamped event logging. |
| Power Management Modes | Four low-power states: Idle (CPU halted, peripherals active), Sleep (peripherals clock-gated), Power Down (all clocks stopped), and Standby (RTC only)-reducing current to <10 µA. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-XC167CI-16F40F | Same die, rated for -40 °C to +125 °C; identical peripherals and memory map. | Required for under-hood automotive or high-temp industrial enclosures where ambient exceeds 85 °C. | Select when extended temperature range is mandatory; otherwise SAF variant offers cost advantage for commercial-grade environments. |
| XC2267M-104F80L AA | Successor 32-bit TriCore™ device with 80 MHz CPU, 1 MB Flash, enhanced CAN FD support, but larger 176-pin LQFP package. | Targets next-gen designs requiring higher compute throughput, CAN FD bandwidth, or ASIL-B compliance-not drop-in compatible. | Choose for new designs needing scalability beyond 16-bit limits; avoid for legacy board reuse due to pinout and voltage domain differences. |
Compared with SAK-XC167CI-16F40F, the SAF-XC167CI-16F20F BB trades extended temperature rating for lower cost and same functional capability; versus XC2267M, it offers proven 16-bit determinism and footprint compatibility at the expense of future-proofing and CAN FD readiness.

Does the SAF-XC167CI-16F20F BB support in-system programming of its Flash memory?
Yes, the SAF-XC167CI-16F20F BB supports in-system programming (ISP) of its 128 KB on-chip Flash via the JTAG interface using Infineon's OCDS debug infrastructure. Sector erase and byte/page programming are implemented in hardware, with no external high-voltage programming required-enabling field firmware updates through ASC or CAN bootloaders.
How many CAN controllers does the SAF-XC167CI-16F20F BB integrate?
The SAF-XC167CI-16F20F BB integrates two fully independent CAN 2.0B controllers (CAN0 and CAN1), collectively referred to as the TwinCAN module. Each supports 32 message objects, hardware acceptance filtering, and automatic retransmission. The module also provides gateway functionality to route messages between the two buses without CPU intervention.
Is the SAF-XC167CI-16F20F BB pin-compatible with other XC167 derivatives?
Yes, the SAF-XC167CI-16F20F BB shares identical pinout and package (144-pin TQFP) with all XC167CI-16F derivatives, including SAK-XC167CI-16F40F and mask-ROM variants.
