General Description

The HT25LC512 is a 512K-bit OTP ROM of which func-

tion and pin assignment are compatible with AT25F512

and can directly replace the AT25F512 for cost down

purposes when the memory in the system is just read

only. There are 512K bits of memory which are orga-

nized as 65536 words of 8 bits each. The HT25LC512

uses a serial interface to sequentially access its data.

The simple serial interface facilitates hardware layout,

increase system reliability, minimize switching noise,

and reduce package size and active pin count. The de-

vice is optimized for use in many commercial and indus-

trial applications where high density, low pin count, low

voltage, and low power consumption are essential. The

device operates at clock frequencies up to 10MHZ.

The HT25LC512 is enabled through the chip select pin

(CS) and accessed via a three-wire interface consisting

of the Serial Input (SI), Serial Output (SO), and the Se-

rial Clock (SCK). The HOLD pin may be used to sus-

pend any serial communication without resetting the

serial sequence.
