MAXQ616

Infrared Remote Control System-on-Chip

Save Power, Cost and Board Space: 16-Bump WLP Reduces Board Space Requirements by 50%

Description

The MAXQ616 is a low-power, 16-bit MAXQ® microcontroller designed for low-power applications including universal remote controls, consumer electronics, and white goods. The device combines a powerful 16-bit RISC microcontroller and integrated peripherals including a universal synchronous/asynchronous receiver-transmitter (USART), an SPI master/slave and I²C communications ports, along with an IR module with carrier frequency generation and flexible port I/O capable of multiplexed keypad control. An internal amplifier eliminates the need for external circuitry to drive the IR receiver pin.

The device includes 80KB of flash memory and 2KB of data SRAM.

For the ultimate in low-power battery-operated performance, the device includes an ultra-low-power stop mode (0.2µA typ). In this mode, the minimum amount of circuitry is powered. Wake-up sources include external interrupts, the power-fail interrupt, and a timer interrupt. The microcontroller runs from a wide 1.70V to 3.6V operating voltage.

MAX14921EVKIT

Evaluation Kit for the MAX14921


Description

The MAX14921 evaluation kit (EV kit) demonstrates a high-accuracy 16-cell battery-management reference design. The MAX14921 is a high-accuracy 16-cell measurement analog front-end (AFE) in an 80-pin TQFP surface-mount package. The EV kit features an ADC and reference, and an isolated interface to a PC through a USB port to easily measure all cell voltages. Cell stacks up to 16 cells or 65V can be monitored, whichever is lower.
The EV kit circuit demonstrates all the features of the device through a GUI application on a Windows®-based PC.

Key Features

  • 16-Cell/65V (max) Stack Operating Voltage Range
  • Built-In Isolated USB Interface to a Windows-Based PC
  • Plugh-and-Play GUI Demonstrates All the Major Features of the MAX14921
  • µC Firmware in C Available Upon Request
  • Screw Terminal Battery Connector
  • Proven PCB Layout
  • Fully Assembled and Tested
