Product details
Overview
SABC165LFHABXUMA1 from Infineon Technologies is a 16-bit C166-family single-chip microcontroller in TQFP-100 package, operating at up to 25 MHz with 5 V supply, featuring 2 KB on-chip IRAM, dual serial channels (asynchronous/synchronous), and two multi-functional timer units. It serves as main controller in industrial motor drives requiring deterministic real-time I/O handling and external memory interfacing.
For engineers reviewing the SABC165LFHABXUMA1 datasheet, SABC165LFHABXUMA1 pinout, SABC165LFHABXUMA1 application, or SABC165LFHABXUMA1 equivalent, key selection criteria include 25 MHz CPU clock timing, TQFP-100 mechanical compatibility, 3 V/5 V supply flexibility, and PEC-driven DMA for high-throughput sensor data acquisition in embedded control systems.
Technical Context
The C165 implements a 4-stage pipeline 16-bit CPU delivering 12.5 MIPS at 25 MHz, with single-cycle context switching support and 16 MByte linear address space spanning code and data. Its peripheral event controller (PEC) enables interrupt-driven, single-cycle data transfers across 8 channels without CPU intervention.
On-chip peripherals include two general-purpose timer units (5 timers total), dual serial interfaces supporting asynchronous UART, synchronous SPI, and high-speed synchronous modes, and programmable chip-select logic for up to five external memory or peripheral regions with configurable bus width (8/16-bit) and multiplexing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C166-family 16-bit with 4-stage pipeline; enables 80 ns instruction cycle at 25 MHz clock. |
| Max Clock Frequency | 25 MHz; supports real-time control loops with sub-40 ns interrupt sample rate. |
| On-Chip RAM | 2 KB IRAM; sufficient for stack, variables, and small real-time buffers without external SRAM. |
| Supply Voltage | 4.5–5.5 V; compatible with standard 5 V industrial power rails and legacy system designs. |
| Package | TQFP-100, 0.5 mm pitch; surface-mount compatible with automated assembly and thermal performance suitable for industrial ambient. |
| I/O Lines | Up to 77 GPIO; includes selectable input thresholds and hysteresis for noise-immune digital sensing in electrically noisy environments. |
| Serial Interfaces | Two independent channels: one supports UART/SCI, the other supports synchronous SPI or high-speed synchronous protocols. |
Pinout & Package
TQFP-100 package (0.5 mm pitch), thermally enhanced for industrial temperature operation (–40°C to +85°C); 100-pin square outline with exposed thermal pad per Infineon mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XTAL1 / XTAL2 | Crystal oscillator inputs | Supports fundamental-mode quartz crystals up to 25 MHz; internal oscillator circuit eliminates need for external clock generator. |
| RSTIN / RSTOUT | Reset input/output | RSTIN accepts active-low reset signal; RSTOUT provides synchronized reset pulse for peripheral initialization during power-up or watchdog timeout. |
| P0L.0–P0L.7 / P0H.0–P0H.7 | Lower/upper data bus (AD0–AD15) | Multiplexed address/data bus for external memory interface; reduces pin count while enabling 16-bit wide external access. |

Key Features
| Feature | Design Value |
|---|---|
| Peripheral Event Controller (PEC) | 8-channel DMA engine with priority arbitration; offloads CPU from repetitive data movement (e.g., ADC result buffering or UART TX/RX). |
| Timer System | Two independent timer units providing 5 total timers - including capture/compare, PWM generation, and input capture for encoder position tracking. |
| Interrupt Architecture | 16-priority-level nested interrupt system with 28 sources and 40 ns minimum sample interval; ensures deterministic response to critical events like overcurrent faults. |
| Power Management | Idle and Power Down modes with wake-up via external interrupt or timer; reduces active current to <100 µA in standby for battery-backed applications. |
| Bootstrap Loader | On-chip ROM-based loader enables field firmware updates via UART without external programmer hardware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAB-C165-L25F | Same die, identical pinout and electrical specs; differs only in ordering code prefix (SAB vs SABC) and tape-and-reel packaging variant. | No functional difference; both support same 25 MHz/5 V operation and TQFP-100 footprint. | Select SAB-C165-L25F if sourcing from legacy distributor stock or requiring non-tray delivery format. |
| SAF-C165-L25F | Identical core, package, and speed grade; SAF prefix denotes extended temperature range (–40°C to +125°C) versus standard –40°C to +85°C. | Required for under-hood automotive or high-ambient industrial enclosures exceeding 85°C ambient. | Choose SAF-C165-L25F when operating ambient exceeds 85°C or when AEC-Q100 qualification is mandated. |
Compared with SABC165LFHABXUMA1, SAB-C165-L25F offers identical functionality in alternate packaging, while SAF-C165-L25F extends thermal capability at no performance trade-off-making the latter essential for high-temperature deployments where junction stability is critical.

FAQ
What is the maximum operating frequency and supply voltage for SABC165LFHABXUMA1?
SABC165LFHABXUMA1 operates at a maximum CPU clock frequency of 25 MHz with a supply voltage range of 4.5 V to 5.5 V. This specification is confirmed in Infineon's C165 Data Sheet V2.0 (December 2000), Section "Operating Conditions" and Table 1 derivative synopsis. The device does not support 3 V operation in this ordering variant.
Does SABC165LFHABXUMA1 include on-chip flash or ROM memory?
No, SABC165LFHABXUMA1 contains 2 KB of on-chip static RAM (IRAM) but no integrated non-volatile program memory. It relies on external ROM, Flash, or EPROM for code storage via its multiplexed external bus interface. Mask-ROM derivatives exist (e.g., SAF-C165-LM), but this specific part number is RAM-only with bootstrap loader support for external firmware loading.
Is SABC165LFHABXUMA1 pin-compatible with other C165 derivatives in TQFP-100?
Yes, all C165 derivatives in TQFP-100 package-including SAB-C165-LF, SAB-C165-L25F, and SAF-C165-L25F-share identical pinout, signal assignment, and mechanical footprint per Figure 2 in the C165 Data Sheet V2.0. Electrical characteristics (e.g., max frequency, temp range) differ, but PCB layout is fully interchangeable.
What development tools are supported for SABC165LFHABXUMA1?
Infineon officially supports C-compilers (e.g., Tasking C166), macro-assemblers, in-circuit emulators (e.g., Lauterbach TRACE32), evaluation boards (C165 Starter Kit), HLL debuggers, and programming boards. The on-chip bootstrap loader also enables UART-based firmware updates without dedicated JTAG hardware, simplifying field deployment and prototyping.
