The TCSl832P is a 2S6K bit high speed cnos pseudo static RAH organized as 32,768
Hords by 8 bits. The TCSl832P utilized one transistor dynamic memory cell ~vith C~IOS
peripheral circuit to provide large capacity, high speed and low power features. System
oriented features include single pot"er supply of SV±lO% torelance. The OE/RFSH input
allotvs t~1I'O types of refresh operation - auto refresh .:lnd self refresh. The TCSl832P
also features static RA1-1 like ~.,rrite function that the input data is ~.Jritten into the
~emory cell at the rising edge of R/W, thus being easy to interface with microprocessor.
The TCSI832P is a pin-compatible tvith 256K bit GIOS static RA~'I - TCS52S7P and is
r.;ouided .J. standard 0.6 inch ~Jid th plas tic DIP.
