AT/TSC8x251G2D

4135F–8051–11/06

NMI

I

Non Maskable Interrupt

Holding this pin high for 24 oscillator periods triggers an interrupt.

When using the Product Name as a pin-for-pin replacement for a 8xC51

product, NMI can be unconnected without loss of compatibility or power

consumption increase (on-chip pull-down).

Not available on DIP package.

P0.0:7

I/O

Port 0

P0 is an 8-bit open-drain bidirectional I/O port. Port 0 pins that have 1s

written to them float and can be used as high impedance inputs. To avoid

any paraitic current consumption, Floating P0 inputs must be polarized to

VDD or VSS.

AD7:0

P1.0:7

I/O

Port 1

P1 is an 8-bit bidirectional I/O port with internal pull-ups. P1 provides

interrupt capability for a keyboard interface.

–

P2.0:7

I/O

Port 2

P2 is an 8-bit bidirectional I/O port with internal pull-ups.

A15:8

P3.0:7

I/O

Port 3

P3 is an 8-bit bidirectional I/O port with internal pull-ups.

PROG#

I

Programming Pulse input

The programming pulse is applied to this input for programming the on-chip

EPROM/OTPROM.

–

PSEN#

O

Program Store Enable/Read signal output

PSEN# is asserted for a memory address range that depends on bits RD0

and RD1 in UCONFIG0 byte (see ).

–

RD#

O

Read or 17th Address Bit (A16)

Read signal output to external data memory depending on the values of

bits RD0 and RD1 in UCONFIG0 byte (see Table 13, Page 20).

P3.7

RST

I

Reset input to the chip

Holding this pin high for 64 oscillator periods while the oscillator is running

resets the device. The Port pins are driven to their reset conditions when a

voltage greater than VIH1 is applied, whether or not the oscillator is running.

This pin has an internal pull-down resistor which allows the device to be

reset by connecting a capacitor between this pin and VDD.

Asserting RST when the chip is in Idle mode or Power-Down mode returns

the chip to normal operation.

RXD

I/O

Receive Serial Data

RXD sends and receives data in serial I/O mode 0 and receives data in

serial I/O modes 1, 2 and 3.

P3.0

SCL

I/O

TWI Serial Clock

When TWI controller is in master mode, SCL outputs the serial clock to

slave peripherals. When TWI controller is in slave mode, SCL receives

clock from the master controller.

P1.6

SCK

I/O

SPI Serial Clock

When SPI is in master mode, SCK outputs clock to the slave peripheral.

When SPI is in slave mode, SCK receives clock from the master controller.

P1.6

SDA

I/O

TWI Serial Data

SDA is the bidirectional TWI data line.

P1.7

SS#

I

SPI Slave Select Input

When in Slave mode, SS# enables the slave mode.

P1.4
