Product details
Overview
ATA8510-GHQW from Microchip (formerly Atmel) is a highly integrated UHF ASK/FSK transceiver with embedded 8-bit AVR® microcontroller, 20KB user Flash, 1KB SRAM, and 1024-byte EEPROM. It operates across 310–318 MHz, 418–477 MHz, and 836–956 MHz bands, supports programmable output power (–12 to +14.5 dBm), and achieves –122.5 dBm FSK sensitivity at 0.75 kbit/s - enabling ultra-low-power wireless sensor nodes and battery-operated remote controls.
For engineers reviewing the ATA8510-GHQW datasheet, ATA8510-GHQW pinout, ATA8510-GHQW application, or ATA8510-GHQW equivalent, this page delivers verified RF performance specs, SPI-controlled service-based polling architecture, fractional-N PLL frequency resolution (93 Hz low-band / 185 Hz high-band), digital RSSI accuracy (±1 dB), and antenna tuning capability - all critical for EN 300 220/FCC Part 15-compliant ISM band designs.
Technical Context
The ATA8510-GHQW implements a dual-path low-IF receiver with digitized IF processing, delivering 55 dB image rejection at 315/433.92 MHz and 64 dB blocking at 1 MHz offset. Its fractional-N PLL enables precise channel selection and supports mixed ASK/FSK telegrams with non-byte-aligned data handling.
Baseband operation is governed by a service-based configuration model: three EEPROM-stored and two SRAM-modifiable service configurations (each with three channels) enable on-the-fly parameter updates in IDLEMode via SPI. The embedded AVR executes custom firmware from 20 KB Flash, managing wake-up patterns, FIFO buffering, and autonomous polling without host intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar UHF ASK/FSK transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs Si4463-B1B-FMR | No integrated MCU; requires external processor; higher Rx sensitivity (–133 dBm @ 1.2 kbps) but no Flash/SRAM | Better suited for host-controlled systems needing maximum sensitivity, not self-contained firmware execution | Choose Si4463 if host MCU handles protocol stack and ultra-low-noise reception is prioritized over firmware autonomy |
| TI CC1120RHBR | Integrated 8051 MCU (4 KB RAM, 32 KB Flash); narrower frequency coverage (27–1050 MHz, no sub-GHz ISM focus); higher typical Rx current (14.3 mA) | Targeted at proprietary PHY layers with advanced packet handling, less optimized for EN 300 220-compliant ASK/FSK | Choose CC1120 if migrating from TI ecosystem and requiring integrated 8051 with extensive RF register control |
Compared with Si4463-B1B-FMR and CC1120RHBR, ATA8510-GHQW uniquely combines 20 KB user Flash, service-based polling, and <5 nA OFFMode current - making it optimal for cost-sensitive, battery-limited devices requiring firmware-defined behavior without host dependency.

FAQ
What is the primary function of the ATA8510-GHQW?
The ATA8510-GHQW is a fully integrated UHF ASK/FSK transceiver with an embedded 8-bit AVR® microcontroller, 20 KB user Flash, and 1 KB SRAM. It performs RF transmission and reception across 310–477 MHz and 836–956 MHz bands while executing custom firmware for protocol handling, polling, and antenna tuning - eliminating the need for an external host MCU in many applications.
Does the ATA8510-GHQW support both ASK and FSK modulation?
Yes, the ATA8510-GHQW natively supports both ASK and FSK modulation. It includes hardware-based ASK shaping to reduce spectral bandwidth and programmable FSK deviation from ±0.375 kHz to ±93 kHz. Mixed ASK/FSK telegrams are supported, and Manchester coding is implemented for both modulation types with verified sensitivity down to –122.5 dBm at 0.75 kbit/s.
How does the service-based configuration model work in the ATA8510-GHQW?
The ATA8510-GHQW organizes RF settings into five services: three stored in EEPROM (fixed) and two in SRAM (modifiable on-the-fly). Each service contains three channels with independent frequency, modulation, and data rate settings. During IDLEMode, SPI commands or firmware can update SRAM services - enabling dynamic adaptation to interference or protocol changes without EEPROM wear or system reset.
What is the significance of the 5 nA OFFMode current in the ATA8510-GHQW?
The typical 5 nA OFFMode current (max 600 nA at 3.6 V / 85°C) allows the ATA8510-GHQW to remain powered for over a decade on a single CR2032 coin cell when used in infrequent wake-up applications like smoke detectors or utility metering. This ultra-low quiescent current is achieved through complete power gating of analog/digital blocks and biasing of NPWRON pins directly from VS.
Can the ATA8510-GHQW perform automatic antenna tuning?
Yes, the ATA8510-GHQW integrates an on-chip variable capacitor controlled via the ANT_TUNE pin (Pin 5) to automatically tune loop antennas to the transmit center frequency. This calibration compensates for manufacturing tolerances and environmental shifts (e.g., temperature, proximity), maintaining optimal RF efficiency without manual adjustment - a key feature confirmed in the 9315G–INDCO–08/15 datasheet.
