Manufacturer: Renesas

Overview: To all our customers Regarding the change of names mentioned in the document, such as Mitsubishi Electric and Mitsubishi XX, to Renesas Technology Corp. The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.) Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names have in fact all been changed to Renesas Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been made to the contents of the document, and these changes do not constitute any alteration to the contents of the document itself. Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices and power devices. Renesas Technology Corp. Customer Support Dept. April 1, 2003 MITSUBISHI MICROCOMPUTERS M37221M4/M8/MA–XXXSP, M37221M6–XXXSP/FP M37221EASP/FP SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER with ON-SCREEN DISPLAY CONTROLLER 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The M37221M4/M8/MA-XXXSP, M37221M6-XXXSP/FP are singlechip microcomputers designed with CMOS silicon gate technology.

They have a OSD, I2C-BUS interface, and PWM, so it is useful for a channel selection system for TV.

The

Key Features

  • of the M37221EASP/FP are similar to those of the M37221MA-XXXSP except that these chips have a built-in PROM which can be written electrically. The differences among the M37221M4/M8/MA-XXXSP, M37221M6-XXXSP/FP are the ROM size and the RAM size as shown below. Accordingly, the following.
