Hardware
OP7100 Subsystems Overview
The OP7100 consists of several subsystems, including a computing module,
serial communication channels, lquid crystal display (LCD), a buzzer, and a
keypad interface. Figure 3-1 provides a block diagram of the OP7100.

Computing Module
The OP7100 computing module consists of a Zilog Z180 microprocessor,
128K of battery-backed static RAM, and 512K of flash EPROM. The
computing module operates in tandem with a real-time clock and a
watchdog timer/microprocessor supervisor.
The Z180 CPU runs at 18.432 MHz, and the LCD controller runs at
9.216 MHz.
The watchdog timer/microprocessor chip provides a watchdog timer
function, power-failure detection, RAM protection, and battery backup.
The real-time clock provides time and date information to applications
running on the OP7100.
The EEPROM is simulated in flash EPROM for consistency
with Rabbit Semiconductor controllers whose software
libraries rely on exchanging information with the EEPROM.
The simulated EEPROM in the OP7100 is unused at the
present time, but addresses 0 and 1 are reserved for furture
use. Do not use these addresses in your application.
