40, 1 to 16 6 to 22

D16 to

I/O, A

Driving Lines 16 to 0

These pins can also be configured as I/O

bi-directional ports for test

- 48, 1 to 5

D22 to

D17

I/O, A

Driving Lines 22 to 17

These pins can also be configured as I/O

bi-directional ports for test

17 23 VDDHV O

High Voltage. 6V

Charge pump high Voltage. This output pin can be

configured as VDD3V or 6V accordingly

18, 30 24, 35 VDD3V P

Supply Voltage. 2.8V to 3.6V

A good decoupling capacitor between VDD3V and

VSS pins is critical for good performance

19 25 VSS P

Ground Voltage. 0V

20 26 VDD18 O

Internal Regulator Output. 1.6V to 2.0V

Typical decoupling capacitors of 0.1



F and 10



should be connected between VDD18 and VSS

21 27 TESTEN I

Test Mode Enable High Active

This pin has an internal weakly pull low resistor

connected. If it is connected high, the chip enters into

Test Mode condition

22 28 SS/SCL I/O

SS/SCL

This pin can be configured as the SCL signal of the

C master or I

C slave controller. When I

C is

enabled, the pin is configured as an open-collector.

While in SPI mode, this pin is configured as the

slave chip select pin

23 29

SCK/

GPIO3

I/O

Port 1.3 GPIO

8051 P1.3 GPIO. This pin can also be configured as

the serial clock from SPI master while SPI interface

is activated

24 30

MOSI/

SDA

I/O

SDA

This pin can be configured as the SDA signal of the

C master or I

C slave controller. In this operation

mode, this pin should also be configured as

open-collector. While SPI interface is selected, the

pin serves as the data port from SPI master to SPI

slave

25 31

MISO/

GPIO2

I/O

Port 1.2 GPIO

8051 P1.2 GPIO. This pin can also be configured as

the output data pin from slave to master for SPI

interface
