S3C84A4/p84a4 produ ct overview 1- 1 1 product overview sam88 rc product family samsung's new sam88rc family of 8-bit single-chip cmos microcontrollers offers a fast and efficient cpu, a wide range of integrated peripherals, and various mask-programmable rom sizes. timer/counters with selectable operating modes are included to support real-time operations. many sam88rc microcontrollers have an external interface that provides access to external memory and other peripheral devices. the sophisticated interrupt structure recognizes up to eight interrupt levels. each level can have one or more interrupt sources and vectors. fast interrupt processing (within a minimum six cpu clocks) can be assigned to specific interrupt levels. S3C84A4x microcontroller the S3C84A4 single-chip microcontroller is fabricated using a highly advanced cmos process. its design is based on the powerful sam88rc cpu core. stop and idle power-down modes were implemented to reduce power consumption. the size of the internal register file is logically expanded, increasing the addressable on-chip register space to 784 bytes. a flexible yet sophisticated external interface is used to access up to 64-kbytes of program and data memory. the S3C84A4 is a versatile microcontroller that is ideal for use in a wide range of general-purpose applications such as cd-rom/dvd-rom drives. using the sam88rc modular design approach, the following peripherals were integrated with the sam88rc cpu core: ? three configurable 8-bit general i/o ports ? one 5-bit general i/o ports ? two 8-bit timers with interval timer ? two 16-bit timers/counters with pwm operating modes 8-bit or capture modes ? voltage level detector circuit embedded. ? two embedded chip selection pins (cs0?cs1) or normal i/o ports ? two programmable 8-bit pwm modules with corresponding output pins ? a/d converter with 4 selectable input pins otp the S3C84A4 microcontroller is also avaiable in otp(one time programmable) version, s3p84a4. the s3p84a4 microcontroller has an on-chip 4k-byte one-time-programmable eprom instead of masked rom. the s3p84a4 is comparable to S3C84A4, both in function and in pin configuration.
