M37221EF-xxxSP

MITSUBISHI MICROCOMPUTERS M37221EF-XXXSP,M37221EFSP SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER with ON-SCREEN DISPLAY CONTROLLER DESCRIPTION The M37221EF-XXXSP and M37221EFSP are single-chip microcomputers designed with CMOS silicon gate technology. They are housed in a 42-pin shrink plastic molded DIP. In addition to their simple instruction sets, the ROM, RAM and I/O addresses are placed on the same memory map to enable easy programming. The M37221EF-XXXSP and M37221EFSP have a PWM output function and a OSD display function, so it is useful for a channel selection system for TV. www.DataSheet4U.com PIN CONFIGURATION (TOP VIEW) HSYNC VSYNC P00/PWM0 P01/PWM1 P02/PWM2 P03/PWM3 P04/PWM4 P05/PWM5 P06/INT2/A-D4 P07/INT1 P23/TIM3 P24/TIM2 P25 P26 P27 D-A P32 CNVSS XIN XOUT VSS 1 2 3 4 5 6 42 41 40 39 38 37 P52/R P53/G P54/B P55/OUT1 P20/SCLK P21/SOUT P22/SIN P10/OUT2 P11/SCL1 P12/SCL2 P13/SDA1 P14/SDA2 P15/A-D1/INT3 P16/A-D2 P17/A-D3 P30/A-D5/DA1 P31/A-D6/DA2 RESET OSC1/P33 OSC2/P34 VCC M37221EF-XXXSP M37221EFSP FEATURES 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 Number of basic instructions ..................................................... 71 Memory size ROM ........................................................ 62 K bytes RAM ....................................................... 1216 bytes ROM for display ......................................... 8 K bytes RAM for display .........................
