C161KLMHABXUMA1

Overview

The C161KLMHABXUMA1 is a 16-bit microcontroller from the Infineon C166 C16xx series. It features a ROMless program memory architecture and operates at a clock speed of 20MHz. The device utilizes an external oscillator type and supports a supply voltage range of 4.5V to 5.5V. It provides 63 I/O lines and includes 2K x 8 bytes of RAM. The component is housed in an 80-QFP (P-MQFP-80-1) surface-mount package. It supports EBI/EMI, SPI, and UART/USART interfaces, with peripherals including POR, PWM, and WDT. The operating temperature range is -40°C to 85°C.

Feature Summary

Built on the C166 core architecture for 16-bit processing
Supports external oscillator configuration
Includes built-in power-on reset, pulse-width modulation, and watchdog timer peripherals

Applications

Automotive electronic control units
Industrial motor control systems
General-purpose embedded applications requiring 16-bit processing

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Infineon Technologies. Procurement should focus on verified substitute part numbers such as the XMC4200F64K256BAXQSA1 or XMC4400F100K512BAXQMA1. Verify compatibility with existing designs before sourcing alternatives.

Selection Notes

Select this component only if legacy C166 architecture support is required. Note that the ROMless design necessitates external code storage. Consider modern replacements like the XMC series for new designs due to the obsolete status of this specific part number.

Part Context

The C161KLMHABXUMA1 belongs to the C161KLM family within the broader C16xx microcontroller lineup. It shares architectural similarities with other C166-based devices but is distinguished by its specific pinout, memory configuration, and package type. It represents an older generation of automotive-grade microcontrollers.
