Description
The H8/300L Series is a series of single-chip microcomputers (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 H8/3834U Series features an on-chip liquid crystal display (LCD) controller/driver. Other on-chip peripheral functions include five timers, a 14-bit pulse width modulator (PWM), three serial communication interface channels, and an analog-to-digital (A/D) converter. Together these functions make the H8/3834U Series ideally suited for embedded control of systems requiring an LCD display. The H8/3834U Series, in particular, features low-voltage A/D converter operation (VCC = AVCC = 2.7 V to 5.5 V), enabling these devices to be used in low-voltage, single power supply systems. On-chip memory is 24 kbytes of ROM and 1 kbyte of RAM in the H8/3833U, 32 kbytes of ROM and 1 kbyte of RAM in the H8/3834U, 40 kbytes of ROM and 2 kbytes of RAM in the H8/3835U, 48 kbytes of ROM and 2 kbytes of RAM in the H8/3836U, and 60 kbytes of ROM and 2 kbytes of RAM in the H8/3837U.The H8/3834U and H8/3837U both include a ZTAT version, featuring a user-programmable on-chip PROM.
