`
`µPD7527A/28A/75CG28E
`4-Bit, Single-Chip
`CMOS Microcomputers
`With FIP® Driver
`
`Description
`The µPD7527A, µPD7528A, and µPD75CG28E are 4-bit,
`single-chip CMOS microcomputers with the µPD7500
`architecture and FIP direct-drive capability.
`The µPD7527 A contains a 2048 x 8-bit ROM and a 128 x
`4-bit RAM. TheµPD7528A contains a 4096 x 8-bit ROM
`and 160 x 4-bit RAM.
`
`The µPD7527A/28A contains two 4-bit general purpose
`registers located outside RAM. The subroutine stack is
`implemented in RAM for greater depth and flexibility.
`The µPD7527A/28A typically executes 67 instructions
`with a 5 µs instruction cycle time.
`
`The µPD7527A/28A has one external and two internal
`edge-triggered hardware-vectored interrupts. It also
`contains an 8-bit timer/event counter and an 8-bit serial
`interface to help reduce software requirements.
`
`Thirty-one high-voltage lines are organized into the 3-bit
`output port 2, the 4-bit output ports 3, 8, and 9, and the 4-
`bit 1/0 ports 4, 5, 10, and 11.
`
`The low power consumption CMOS process allows the
`use of a power supply between 2.7 and 6.0V. Current
`consumption is less than 3.0 mA maximum, and can be
`further reduced in the halt and stop power-down modes.
`
`The µPD75CG28E is a piggyback EPROM version of the
`µPD7527A/28A.
`Pin-compatible
`and
`function(cid:173)
`compatible with the final, masked versions of the
`µPD7527A/28A, the µPD75CG28E is used for prototyp(cid:173)
`ing and for aiding in program development.
`
`Features
`□ 67 instructions
`□ Instruction cycle:
`-
`Internal clock: 3.3µs/600 kHz, 5 V
`- External clock: 3.3 µs/600 kHz, 5 V
`□ Upwardly compatible with the µPD7500 series
`product family
`□ 4,096 x 8-bit ROM (µPD7528A/75CG28E)
`2,048 x 8-bit ROM (µPD7527 A)
`□ 160 x 4-bit RAM (µPD7528A/75CG28E)
`128 x 4-bit RAM (µPD7527A)
`□ 351/0 lines
`□ 31 high-voltage output lines that can directly drive a
`vacuum fluorescent display (FIP)
`□ Can select either a pull-down resistor or open-drain
`output per 31 high-voltage outputs (mask optional)
`FIP is the registered trademark for NEC's fluorescent Indicator panel (vacuum
`fluorescent display).
`
`50275 (NECEL-509)
`
`□ Vectored interrupts: one external, two internal
`□ 8-bit timer/event counter
`□ 8-bit serial interface
`□ Standby function (HALT, STOP)
`□ Data retention mode
`□ Zero-cross detector on P0o/lNT0 input (mask
`optional)
`□ System clock (µPD7527 A/7528A/75CG28E): on-chip
`RC oscillator
`□ CMOS technology
`□ Low power consumption
`□ Single power supply

`Pin Functions, µPD75CG28E EPROM
`MSEL
`Changes the addressing area of the external EPROM
`and the on-chip RAM (with a pull-down resistor). Con(cid:173)
`necting a jumper between socket pins 27 (MSEL) and 28
`(Yoo) selects µPD7527 A mode (2-Kbyte EPROM, 128 x 4-
`bit RAM). Leaving MSEL open selects µPD7528A mode
`(4-Kbyte EPROM, 160 x 4-bit RAM).
`
`Ao-A10
`Output the low-order 11 bits of the program counter
`(PC0-PC10). Used as EPROM address signals.
`
`A11
`When MSEL is high level, A11 outputs high-level signals.
`When MSEL is open, A11 outputs the MSB of the PC,
`which is used as the most significant address signal of
`the 4-Kbyte EPROM 2732.
`
`II
`
`lo-17
`Input data read from the EPROM.
`
`CE
`
`Outputs the chip enable signal to the EPROM.
`Voo
`Pin 26 is electrically equivalent to the bottom Voo pin
`and is used to supply Vee to the EPROM. Pin 28 is elec(cid:173)
`trically equivalent to the bottom Voo pin and is used to
`supply the high level signal to MSEL. Pin 1 connects to
`pin 21 of µPD75CG28E.
`
`Vss
`Pin 14 is electrically equivalent to the bottom Vss pin in
`voltage, and is connected to the EPROM GND pin. Pin
`22 is electrically equivalent to the bottom Vss pin and is
`used to supply the OE signal to the EPROM.
`
`Instruction Set
`Refer to the User's Manual. The instruction set appears
`also as subset A4 in the data sheet for the µPD7500 se(cid:173)
`ries of single-chip microcomputers.
