Figure 4 illustrates the block diagram of one possible
scheme for programming the ispLSI devices. For details
on the operation of the internal state machine and pro-
gramming of the device please refer to the ISP Architecture
and Programming section in this Data Book.
The device identifier for the ispLSI 1032 is 0000 0011
(03 hex). This code is the unique device identifier which
is generated when a read ID command is performed.
The ispLSI devices are the in-system programmable
versions of the Lattice Semiconductor High-Density pro-
grammable Large Scale Integration (pLSI) devices. By
integrating all the high voltage programming circuitry on-
chip, programming can be accomplished by simply shifting
data into the device. Once the function is programmed,
the non-volatile E

CMOS cells will not lose the pattern
even when the power is turned off.
All necessary programming is done via five TTL level
logic interface signals. These five signals are fed into the
on-chip programming circuitry where a state machine
