Product details
Overview
SAF-XC164S-16F40F BB from Infineon Technologies is a 16-bit single-chip microcontroller based on the C166SV2 core, featuring 128 KB on-chip Flash, 40 MHz CPU clock (25 ns instruction cycle), 2 KB DPRAM + 4 KB DSRAM + 2 KB PSRAM, and integrated peripherals including dual ASC/SSC interfaces, CAPCOM6 PWM unit, 14-channel 10-bit ADC (2.55 µs conversion), and GPT12E timer. It targets real-time motor control and industrial embedded systems requiring deterministic interrupt response down to 50 ns.
For engineers reviewing the SAF-XC164S-16F40F BB datasheet, SAF-XC164S-16F40F BB pinout, SAF-XC164S-16F40F BB application, or SAF-XC164S-16F40F BB equivalent, key selection criteria include its 100-pin TQFP package, 40 MHz PLL-based clock generation, 16-priority-level interrupt system with 75 sources, and on-chip debug support via JTAG for real-time firmware validation in safety-critical motion control loops.
Technical Context
The SAF-XC164S-16F40F BB implements a 5-stage pipelined C166SV2 CPU with zero-cycle jumps, 1-cycle 16×16 multiply, and MAC instructions-enabling efficient execution of motor control algorithms. Its memory subsystem includes linear 16 MB address space, dual-port RAM for concurrent CPU/peripheral access, and Flash with background erase/write capability.
Peripheral integration centers on real-time signal conditioning and actuation: the 14-channel ADC supports simultaneous sampling triggers from CAPCOM or GPT12E; CAPCOM6 provides 3–6 independent PWM channels with dead-time insertion; and the 5-timer GPT12E supports position capture, pulse width measurement, and quadrature decoding for BLDC/PMSM commutation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C166SV2 16-bit RISC-like core with 5-stage pipeline and zero-cycle jump execution for deterministic loop timing. |
| Clock Speed | 40 MHz CPU clock (25 ns instruction cycle); achieved via on-chip PLL with selectable multiplication factors (1:0.15 to 1:10). |
| Flash Memory | 128 KB on-chip Flash with background programming and sector erase-supports in-field firmware updates without halting execution. |
| RAM Configuration | 2 KB dual-port RAM (DPRAM) + 4 KB data SRAM (DSRAM) + 2 KB program/data SRAM (PSRAM) for segregated code/data/stack allocation. |

FAQ
What is the maximum operating temperature range for SAF-XC164S-16F40F BB?
The SAF-XC164S-16F40F BB is rated for operation from −40 °C to +85 °C ambient temperature, validated per Infineon's industrial qualification standards. Thermal resistance values (RΘJC = 20 K/W, RΘJL = 35 K/W) assume standard 4-layer PCB with 2 oz copper and thermal vias under the package-derating applies above 70 °C ambient in sealed enclosures.
Does SAF-XC164S-16F40F BB support in-system programming via JTAG?
Yes-SAF-XC164S-16F40F BB supports full in-system programming (ISP) and debugging via its 5-pin JTAG interface (TCK, TMS, TDI, TDO, TRST). The on-chip bootstrap loader enables Flash programming without external ROM, and OCDS allows real-time memory read/write during active execution for firmware patching.
Can the ADC operate synchronously with CAPCOM6 PWM events?
Yes-the 14-channel ADC can be triggered directly by CAPCOM6 compare events or GPT12E timer overflows, enabling precise current sampling at defined points within the PWM period (e.g., center-aligned sampling). This synchronization is hardware-configured via the Peripheral Event Controller (PEC) and requires no CPU intervention.
Is the SAF-XC164S-16F40F BB RoHS compliant and halogen-free?
Yes-SAF-XC164S-16F40F BB uses a Green TQFP package certified RoHS compliant (2011/65/EU) and halogen-free per IEC 61249-2-21. The "Green" designation in Table 1 confirms compliance with Infineon's material declaration requirements, including ≤900 ppm bromine and ≤900 ppm chlorine in homogeneous materials.
