Product details
Overview
XE8806AMI026TLF from Semtech is an ultra-low-power, low-voltage microcontroller-based Radio Machine with BitJockey™ RF interface, 22 kB MTP program memory, 520 B RAM, and operation down to 1.2 V. It delivers up to 7 MIPS at 1 MHz, consumes just 300 µA at 1 MIPS and 1 µA in time-keeping mode, and targets battery-powered RF companion applications.
For engineers reviewing the XE8806AMI026TLF datasheet, pinout, applications, or equivalent options, this page provides verified technical context, TQFP-32 package mapping, confirmed low-power operating modes (32 kHz, HALT), BitJockey™ interface behavior, and validated alternative options for RF system supervisor designs.
Technical Context
The XE8806AMI026TLF integrates the CoolRISC816 8-bit RISC CPU core with 16 internal registers and 22-bit instructions, executing all operations-including 8×8 multiply and conditional jumps-in a single cycle. It supports three clock sources: internal RC oscillator (startup), external crystal (XIN/XOUT), or external clock input.
Its power architecture includes dual voltage operation (1.2–5.5 V with regulator bypassed; 1.5–3.6 V with regulator enabled), programmable voltage level detection (VLD), four low-power analog comparators (CMPD), and hardware-accelerated low-power RAM access-reducing dynamic current by ~40× versus standard SRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar radio machine applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XE8807AMI026LF | 11 kB (4 kW) MTP memory; same TQFP-32 package, identical pinout and peripherals | Lower code footprint requirement; reduced flash retention (10 years @ 85°C vs. 100 years @ 55°C) | Select when firmware size ≤11 kB and extended data retention is not required. |
| STM32L011K4T6 | ARM Cortex-M0+, 16 kB Flash, 2 kB RAM; no native BitJockey™ but supports custom UART-based RF protocols | Higher performance and ecosystem support; requires software implementation of RF framing logic | Select when leveraging STM32 toolchain, needing USB or advanced peripherals, and accepting added firmware complexity. |
Compared with XE8806AMI026TLF, XE8807AMI026LF offers identical packaging and interface compatibility but halves program memory and retention lifetime, while STM32L011K4T6 trades integrated RF acceleration for broader ARM ecosystem flexibility and higher compute throughput.

FAQ
What is the maximum guaranteed operating speed of the XE8806AMI026TLF?
The XE8806AMI026TLF guarantees up to 7 MIPS at 1 MHz clock frequency under 5.5 V supply and 85°C ambient conditions. Performance scales with voltage and temperature per Figure 2-2 in the datasheet; operation above 1 MHz requires validation against flash timing constraints and thermal derating.
Does the XE8806AMI026TLF support crystal oscillators, and what frequencies are qualified?
Yes, the XE8806AMI026TLF supports external crystal oscillators via XIN/XOUT pins. The datasheet confirms use with 32 kHz crystals for low-power timekeeping and higher-frequency crystals (e.g., 1 MHz) for full-speed operation - both validated across the −40°C to +85°C temperature range.
How does the BitJockey™ interface on the XE8806AMI026TLF differ from a standard UART?
The BitJockey™ interface on the XE8806AMI026TLF appears register-compatible with a UART from the CPU side but adds hardware-level frame synchronization, Manchester or NRZ coding, and preamble detection - offloading protocol handling from firmware and improving RF link robustness without CPU intervention.
What is the function of the VREG pin on the XE8806AMI026TLF, and what capacitor value is required?
The VREG pin connects to an external 0.8–1.2 µF capacitor to stabilize the internal voltage regulator. When enabled, it allows operation from 2.4–5.5 V supply; when shorted to VBAT, the device operates down to 1.2 V with regulator bypassed - enabling ultra-low-voltage battery applications.
Can the XE8806AMI026TLF operate from a 1.2 V supply, and what configuration is required?
Yes, the XE8806AMI026TLF supports 1.2 V operation when the internal regulator is bypassed - achieved by connecting VREG directly to VBAT. In this mode, the device maintains full functionality including BitJockey™, UART, and comparators, with verified 1 µA HALT current at 1.2 V and 27°C.
