XE8806AMI026TLF

Overview

The XE8806AMI026TLF is a member of the Semtech XE8806A/XE8807A family, classified as an ultra low-power, low-voltage microcontroller-based Radio Machine. It features the Coolrisc816 CPU core with up to 7 MIPS performance and includes the BitJockey™ peripheral for radio communication. The device provides 22 kB (8 kW) of MTP program memory and 520 B of RAM. It operates within a supply voltage range of 1.2 V to 5.5 V and supports independent RC and crystal oscillators.

Feature Summary

• Ultra low-power MCU with 300 µA consumption at 1 MIPS and 1 µA time-keeping mode
• Integrated BitJockey™ UART-type peripheral specialized for radio communication
• 22 kB MTP program memory with 100-year retention at 55°C
• Low-voltage operation from 1.2 V to 5.5 V with internal voltage regulator

Applications

• RF companion chip
• Portable, battery-operated instruments
• Metering devices
• Remote control systems
• HVAC control units

Procurement Notes

Verify that the ordering suffix 'TLF' corresponds to the TQFP32 package variant listed in the official datasheet. Confirm the temperature range matches the -40°C to 85°C specification for the MTP version. Ensure compatibility with the required flash programming tools for the Multiple-Time-Programmable memory architecture.

Selection Notes

Select this model over the XE8807A when 22 kB of instruction memory is required, as the XE8807A offers only 11 kB. Choose the MTP version for field-upgradable firmware capabilities compared to the ROM-based XE8806ARI variants. Consider the TQFP32 package constraints regarding Port A and Port D pin multiplexing if analog or digital I/O density is critical.

Part Context

This component belongs to the XE8800 series of Radio Machines designed by Semtech. It utilizes the Coolrisc816 RISC core, which executes instructions in a single clock cycle and includes an 8x8 multiplier. The series integrates specific peripherals like the BitJockey™ interface and Voltage Level Detector (VLD) to support battery-powered wireless applications efficiently.

Replacement Considerations

The XE8807AMI026LF serves as a lower-memory alternative within the same family. For ROM-based requirements, the XE8806ARI026LF is the corresponding non-volatile memory variant. Verify package compatibility when substituting between bare die, SO-28, SO-24, and TQFP32 options.
