Analog Devices Inc./Maxim Integrated MAXQ616V-L001+T

Overview

MAXQ616V-L001+T from Maxim Integrated is a 16-bit RISC microcontroller System-on-Chip optimized for infrared remote control applications, featuring 80KB flash, 2KB SRAM, integrated IR carrier generation, 200mA IR driver sink current at 1.8V, and ultra-low-power stop mode (0.2µA typ). It serves as the central controller in universal remotes for smartphones and tablets.

For engineers reviewing the MAXQ616V-L001+T datasheet, MAXQ616V-L001+T pinout, MAXQ616V-L001+T application, or MAXQ616V-L001+T equivalent, key selection criteria include IR learning amplifier integration, 1.67V–3.6V supply range, 12MHz internal oscillator, stop-mode current budget, and WLP-16 package footprint constraints.

Technical Context

The MAXQ616V-L001+T implements a 16-bit MAXQ RISC core with 33 instructions, three independent data pointers, and dedicated code-space read pointer-enabling efficient firmware execution in battery-powered IR remotes. Its memory subsystem includes 80KB on-chip flash for application code and 2KB SRAM for runtime variables and stack.

Hardware peripherals are tightly coupled to IR system requirements: an integrated IR learning amplifier eliminates external op-amps; the IR transmit driver delivers ≥200mA sink current at 1.8V; and automatic carrier frequency generation supports standard protocols without software timing loops. The 8kHz nanopower ring oscillator enables wake-up from stop mode with sub-µA overhead.

FAQ

What is the maximum sink current capability of the IRTX pin on the MAXQ616V-L001+T?

The IRTX pin on the MAXQ616V-L001+T provides a minimum sink current of 200mA at 1.8V, enabling direct drive of standard high-output IR LEDs without external transistors. This specification is guaranteed over temperature and process variation per the MAXQ616 datasheet Rev. 1. The MAXQ616V-L001+T maintains this performance across its full 1.67V–3.6V supply range, with derating above 1.8V.

Does the MAXQ616V-L001+T require an external crystal or resonator?

No, the MAXQ616V-L001+T includes a factory-trimmed 12MHz internal oscillator that meets timing requirements for IR carrier generation and UART communication without external components. The XTAL pin is not used in standard operation, simplifying layout and reducing BOM cost. The MAXQ616V-L001+T achieves ±1% frequency accuracy over voltage and temperature using this internal source.

How does the IR learning amplifier in the MAXQ616V-L001+T improve remote control functionality?

The integrated IR learning amplifier in the MAXQ616V-L001+T conditions raw photodiode signals with programmable gain and filtering, enabling reliable capture of unknown or proprietary IR protocols without external op-amps. It provides >60dB dynamic range and DC-coupled response down to 1kHz. This allows the MAXQ616V-L001+T to serve as a universal learning remote controller with minimal external circuitry.

What is the typical current consumption of the MAXQ616V-L001+T in stop mode?

The MAXQ616V-L001+T draws 0.2µA typical current in stop mode at +25°C with power-fail monitor disabled, supporting multi-year battery life in remote controls. This value is measured with only the 8kHz ring oscillator and wake-up logic active. The MAXQ616V-L001+T maintains this ultra-low quiescent current while retaining SRAM contents and responding to external interrupts within microseconds.

Is the MAXQ616V-L001+T pin-compatible with other devices in the MAXQ616 family?

Yes, the MAXQ616V-L001+T shares identical pinout and package (16-bump WLP) with other speed- and temperature-grade variants in the MAXQ616 family, including MAXQ616V-L000+T and MAXQ616V-L002+T. Firmware and PCB layout are interchangeable across these variants, differing only in internal flash configuration and screening specifications. The MAXQ616V-L001+T is rated for commercial temperature range (0°C to +70°C).
