MITSUBISHI MICROCOMPUTERSPCA4360MELPS 760 EVALUATION BOARD (MS0760-XXXP. MS0761-XXXP)DESCRIPTIONThe PCA4360 evaluation board is used as an evaluationboard for MELPS 760 4-bit single-chip computers.When used in the external ROM mode, this board consists·of the evaluation chip (M50760-000P) and the programEPROM (M5L2716K) possessing equivalent functions to themasked ROM M50760-XXXP and M50761-XXXP. When creatingthe mask for a developed program, this board is suitablefor verification and running tests.FEATURES• Board computer equivalent to M50760-XXXP, M50761-XXXP• Simple program modification using an EPROM• Connection to user's system by means of a cable• Built-in clock gene~torAPPLICATIONSProgram and applications equipment. development forMELPS 760 4-bit Single-chip microcomputersFUNCTIONThe evaluation chip (M50760-000P) outputs the value of theprogram counter, and reads and executes the instructionstored in the appropriate EPROM address.It is possible to have this board emulate the operation of asingle-chip microcomputer.SPECIFICATIONSItemApplicable microcomputerClock frequencyCycle timeI VoltagePower supply ICurrentConnection with usersystemICF 400kHzSpecificationM50760-XXX P, M50761-XXX PICR 200-400kHz10,us5V±5%, single0.5mA typoAccessory cableI Jl For user system connection (20pin)ConnectorsJ ,J2 2-pin angle pin header for power supplyOuter dimensions 100 (L) X 150 (W) X 20 (H) mmCONFIGURATIONAs can be seen in the block diagram, the PCA4360 consistsof the following hardware:(1) Evaluation chip and peripheral circuit.
