COMBI Unified Remote
Description
IR Remote MCUs have a remote out port internally. IR Remote is widely used in verierty appliances like TV, DVD...etc.( Remote means remote controller )

ABOV's 8 bit Remote MCUs are normally used to Unified Remote. Unified Remote is a remote which can controlles more than two formats ( Many formats are unified at one unified remote. so we call it as unified remote). So it is more complicate and requires more perfomance than single remote. ( See Single Remote MCU )

So, 8 bit Reomcon MCUs are used to Unified Remote and 4 bit Remote MCUs are used to single remote normally.

ABOV's Remote MCUs have a exclusive port which is used to drive a IR-LED. It can drive high current for IR-LED and generate synced signals with specific frequency, 37.5KHz which called carrier frequency.

This seriese has M8051 Core which is compatible with standard 8051 but much faster. Besides, part of FLASH rom can be used as a EEPROM which can be modified while operating time. Therefor it can keep configuration data while battery is changing without old style condenser backup.

Technical Infomation
Rom type description
COMBI FLASH OTP MASK
It has OCD(On Chip Debugger) inside. So it is possible to debug when the MCU is attached to system without extra emulator. Just 2 line connection, interface board and free software are requried.

Because of that it is a 8051 compatilbe MCU, every 8051 C compilers can be used such as Keil-C or SDCC.
