APPLICATIONS
Telephony:
– RAM expansion for stored numbers in repertory
dialling (e.g. PCD33xxA applications)
General purpose RAM for applications requiring
extremely low current and low-voltage RAM retention,
such as battery or capacitor-backed.
Radio, television and video cassette recorder:
– channel presets
General purpose:
– RAM expansion for the microcontroller families
PCD33xxA, PCF84CxxxA, P80CLxxx and most other
microcontrollers.

GENERAL DESCRIPTION
The PCF8570 is a low power static CMOS RAM,
organized as 256 words by 8-bits.
Addresses and data are transferred serially via a two-line
bidirectional bus (I
2
C-bus). The built-in word address
register is incremented automatically after each written or
read data byte. Three address pins, A0, A1 and A2 are
used to define the hardware address, allowing the use of
up to 8 devices connected to the bus without additional
hardware.
