8-bit Data Bus Peripheral
Processor Connection
Figure 22 illustrates the connection of a TS68882 to a TS68008 as a peripheral proces-
sor over an 8-bit data bus. The TS68882 is configured to operate over an 8-bit data bus
when the SIZE pin is connected to GND. The eight least significant data pins (D0-D7)
must be connected to the twenty four most significant data pins (D8-D31) when the
TS68882 is configured to operate over an 8-bit data bus (i.e., connect D0 to D8, D16
and D24; D1 to D9, D17, and D25;... and D7 to D 15, D 23, and D31). The DSACK0 pin
of the TS68882 is connected to the DTACK pin of the TS68008, and the DSACK1 pin is
not used.
When connected as a peripheral processor, the TS68882 chip select (CS) decode is
system dependent, and the CS must be decoded in the supervisor or user data spaces.
Preparation For
Delivery
Certificate of
Compliance
ATMEL-Grenoble offers a certificate of compliance with each shipment of parts, affirm-
ing the products are in compliance with MIL-STD-883 and guaranteeing the parameters
are tested at extreme temperatures for the entire temperature range.
Handling
Devices must be handled with certain precautions to avoid damage due to accumulation
of static charge. Input protection devices have been designed in the chip to minimize the
effect of this static buildup. However, the following handling practices are
recommended:
a) Device should be handled on benches with conductive and grounded surface.
b) Ground test equipment, tools and operator.
c) Do not handle devices by the leads.
d) Store devices in conductive foam or carriers.
e) Avoid use of plastic, rubber, or silk.
f) Maintain relative humidity above 50%, if practical.
