M3826

3826 Group (One Time PROM version) SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER REJ03B0181-0100 Rev.1.00 Sep 06, 2006 DESCRIPTION The 3826 group is the 8-bit microcomputer based on the 740 family core technology. The 3826 group has the LCD drive control circuit, an 8-channel A/ D converter, D/A converter, serial interface and PWM as additional functions. The various microcomputers in the 3826 group (One Time PROM version) include variations of internal memory size and packaging. This datasheet describes only the One Time PROM version (ROM 60 K version) of 3826 Group. www.DataSheet4U.com Serial interface Serial I/O1 ...................... 8-bit ✕ 1 (UART or Clock-synchronous) Serial I/O2 .................................... 8-bit ✕ 1 (Clock-synchronous) PWM output .................................................................... 8-bit ✕ 1 A/D converter ............. 10-bit ✕ 8 channels or 8-bit ✕ 8 channels D/A converter .................................................. 8-bit ✕ 2 channels (used as DTMF and CTCSS function) LCD drive control circuit Bias ......................................................................... 1/2, 1/3 Duty .................................................................. 1/2, 1/3, 1/4 Common output ................................................................ 4 Segment output .............................................................. 40 2 Clock generating circuits (connect to external ceramic resonator or quartz-crystal oscilla...
