MCUs with built-in LCD driver optimised for data loggers

LAPIS Semiconductor has recently announced the availability of 32bit microcontrollers suitable for data loggers used in logistics for acquisition and management of environmental information during package shipment.

The ML630Q464/466 are the first ICs in the industry to integrate all major functions required for data logging (USB, high speed clock generation, LCD driver, high-accuracy RC oscillation type AD converter), data acquisition (temperature, humidity, acceleration and other), data display, and PDF file generation on a single chip.

The ICs provide PDF file generation and integrate key functions for USB data logging on one chip, which is said to reduce board space by 30%.

The MCUs use an ARM Cortex M0+ 32bit CPU core to achieve high performance with low power consumption and log data can be converted to PDF in 4s. Also, combining the customer’s AES encryption program with the built-in AES function and random number generator allows users to generate password-protected PDF files.

According to the company, MCUs achieve a standby current consumption of 0.8µA by supporting 4 low power modes, which enables operation for up to 380 days using a single coin battery.

A reference kit is provided, including various software code for operating the USB flash memory and generating PDF files, all necessary documentation, and usage methods for power management.

The ML630Q46x are said to clear ±30kV, exceeding the measurement instrument limit of test voltage level 4 of the IEC 61000-4-2*4 standard.

In addition, the products inherit the company’s robust noise immunity, making it possible to achieve stable operation even under severe conditions.
