The ML620Q503H/504H are based on LAPIS’ proprietary 16-bit low power RISC microcontroller core and are available with two different Flash sizes (64 KB/32 KB). These MCUs are the ideal products for use at the center of a data logger when neither a USB port or LCD are required. To enable asset tracking data collection, there are multiple serial ports to connect multiple digital sensors and a wireless or other external communication device. They have two RC-ADCs for measuring temperature precisely and have multiple clock modes. In addition, the different power saving modes contribute to long battery life for any battery operated device. HALT mode brings the current down to 0.45 µA.
