Product details

16-bit RISC core with on-chip LCD drive

The MAXQ2000-RAX is a 16-bit RISC microcontroller from the MAXQ® family, running at 20 MHz. A built-in LCD controller handles segment-drive directly, so a separate display driver IC is unnecessary for character or simple graphic panels. The peripheral set also includes a programmable watchdog timer, power-on reset, and PWM outputs for dimming or motor control. Serial connectivity covers 1-Wire®, SPI, and UART/USART — the 1-Wire interface is useful for temperature sensors or EEPROMs on a single data line, while the SPI port can talk to ADCs or DACs at the core clock rate.

Package, power, and temperature envelope

Housed in a 68-lead VFQFN with an exposed pad (10x10 mm body), the MAXQ2000-RAX is a surface-mount part.

Frequently asked questions

What is the MAXQ2000-RAX's core speed and memory?

The core runs at 20 MHz. Program memory is 64 KB of flash (organized as 32K x 16), and data RAM is 2K x 8. This combination suits control applications with moderate data logging or display buffers.

Does the MAXQ2000-RAX have an LCD controller on chip?

Yes, it includes a built-in LCD controller peripheral.

Is the MAXQ2000-RAX RoHS compliant?

No, it is marked RoHS non-compliant. This means the part contains lead (Pb) above the 0.1 % threshold. It is suitable for applications with a RoHS exemption, such as certain industrial, medical, or aerospace equipment. Confirm your assembly process can accept non-RoHS material.
