AGB64LV01-QC-E

Specialized ICS Overview

The AGB64LV01-QC-E is a specialized microcontroller designed for GUI rendering and LCD control. It operates on a 3.3V supply with an operating frequency up to 20 MHz. The device integrates an LCD controller, microprocessor, UART, timers, and SPI master peripherals. It features 80 pins in a PQFP package (14x20 mm) and supports external asynchronous SRAM (minimum 128Kx8) and serial flash memory. The chip manages graphic images and UI objects directly to the display, reducing host processor load.

Specialized ICS Feature Summary

• Integrated LCD controller supporting displays up to full VGA resolution with adjustable bias voltage.
• Built-in HTML-based GUI creation tools converting HTML, JPEG, and GIF into executable pages.
• Processor-independent architecture compatible with 8/16/32-bit microcontrollers and DSPs.
• Includes RS232 interface (up to 115,200 bps), SPI master, and touch-screen decoding support.

Specialized ICS Applications

• Monochrome and color LCD displays requiring dedicated GUI management.
• Industrial control panels with resistive touch screens.
• Embedded systems utilizing Amulet Easy GUI Browser firmware.
• Applications needing reduced host CPU overhead for graphics rendering.

Specialized ICS Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature range. Confirm availability of the recommended external components, such as the AT45DB041B DataFlash and ADS7846 touch controller, for complete system design. Ensure the host microcontroller interfaces align with the chip's address and data bus requirements.

Specialized ICS Selection Notes

Select this component when offloading complex GUI rendering from the main processor is required. Ensure the application provides at least 128Kx8 external SRAM and supports a crystal oscillator up to 20 MHz. Verify that the target LCD panel matches the supported duty cycles and that the host system can interface via the parallel address/data bus or SPI.

Specialized ICS Part Context

This part belongs to the Amulet Easy GUI Browser series, which combines an LCD controller and user interface chip. It eliminates the need for complex pixel-drawing code by rendering GUI pages directly to the LCD. The series allows embedded designs to run on smaller processors with less RAM and ROM, significantly reducing development time.

Specialized ICS Replacement Considerations

No direct public substitutes are listed. Alternative solutions require redesigning the GUI firmware and hardware interface. If replacing, ensure the new component supports similar LCD timing parameters and offers comparable SPI/UART connectivity for flash and touch controllers.

Specialized ICS FAQ

What is the minimum external SRAM size required?

The minimum size is 128K x 8 bits. The speed grade depends on the system clock frequency.

How is the system clock configured?

An external crystal oscillator up to 20 MHz is used. Crystal frequency selection is determined by the CFS1 and CFS2 pin states.

Does the chip support touch screens?

Yes, it supports Burr-Brown touch-screen controllers (ADS7843 and ADS7846) for decoding 4-wire resistive touch panels via SPI.
