Product details
Overview
MAXQ616V-L000+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, IR learning amplifier, and 200mA IR transmit driver at 1.8V. It operates from 1.67V to 3.6V and achieves 0.2µA typical stop-mode current.
For engineers reviewing the MAXQ616V-L000+T datasheet, MAXQ616V-L000+T pinout, MAXQ616V-L000+T application, or MAXQ616V-L000+T equivalent, key selection considerations include ultra-low-power stop mode (0.2µA), on-chip IR transmitter driver capability, integrated 12MHz oscillator, 16-bump WLP package footprint, and support for universal remote control firmware with keypad multiplexing and IR learning.
Technical Context
The MAXQ616V-L000+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-constrained IR remotes. Its memory subsystem includes 80KB of on-chip flash for application and protocol stack storage and 2KB of SRAM for runtime variables and IR buffer handling.
Peripherals are tightly integrated for remote control functionality: an IR module provides carrier-frequency generation (30–60kHz), modulation, learning amplifier input, and a high-current (200mA min @ 1.8V) IR LED driver output; plus USART, SPI, I²C, dual 16-bit timers, and 8kHz nanopower wake-up oscillator for low-latency resume from stop mode.

FAQ
What is the operating voltage range supported by the MAXQ616V-L000+T?
The MAXQ616V-L000+T operates from 1.67V to 3.6V, enabling compatibility with single-cell alkaline, lithium primary, and rechargeable batteries. This wide range allows the MAXQ616V-L000+T to remain functional even as battery voltage declines, supporting extended operational life in remote control applications without premature shutdown.
Does the MAXQ616V-L000+T include an integrated IR transmitter driver?
Yes, the MAXQ616V-L000+T integrates a high-current IR transmit driver capable of sinking ≥200mA at 1.8V on the IRTX pin. This allows direct connection to standard IR LEDs without external transistors or driver ICs, reducing bill-of-materials cost and PCB area-key advantages confirmed in the MAXQ616V-L000+T datasheet and application schematics.
What is the typical stop-mode current consumption of the MAXQ616V-L000+T?
The MAXQ616V-L000+T achieves 0.2µA typical stop-mode current at +25°C with power-fail monitor disabled. This ultra-low quiescent current is measured and specified in the official MAXQ616V-L000+T datasheet and enables multi-year battery life in coin-cell-powered remote controls-a defining specification of the MAXQ616V-L000+T.
How much on-chip memory does the MAXQ616V-L000+T provide?
The MAXQ616V-L000+T includes 80KB of on-chip flash memory for firmware and IR protocol storage, and 2KB of data SRAM for runtime variables and signal buffers. These memory capacities are explicitly stated in the MAXQ616V-L000+T product brief and are sufficient to host multiple IR command sets and learning buffers without external memory.
Is an external crystal required for the MAXQ616V-L000+T to operate?
No, the MAXQ616V-L000+T features an internal 12MHz oscillator that requires no external components. While an external clock source can be applied via the XTAL/CLKIN pin, the MAXQ616V-L000+T defaults to its internal oscillator-reducing component count, PCB area, and cost. This capability is documented in the MAXQ616V-L000+T datasheet's clocking section.
