The H8/300L Series is a series of single-chip microcontrollers (MCU: microcomputer unit) built around the high-speed H8/300L CPU and equipped with peripheral system functions on-chip.
Within the H8/300L Series, the H8/3714 Series microcontrollers are equipped with high-voltage pins. On-chip peripheral functions include a vacuum fluorescent display (VFD) controller/driver, timers, a 14-bit pulse width modulator (digital-to-analog converter), two serial communicationinterface channels, and an analog-to-digital converter. Together, these functions make the H8/3714 Series ideally suited for embedded control of systems requiring a vacuum fluorescent display. On-chip memory is 16 kbytes of ROM and 384 bytes of RAM in the H8/3712, 24 kbytes of ROM and 384 bytes of RAM in the H8/3713, or 32 kbytes of ROM and 512 bytes of RAM in the H8/3714, providing a choice for systems of different sizes. The ZTAT™* versions of the H8/3714 come with user-programmable PROM.
