Notes:
1. The values shown are typical. The typical value varies as shown, based on how many IMP on-chip peripherals are enabled
    and the rate at which they are clocked.
2. LPREC = 0. Divider = 2.
3. LPREC = 1. Divider = 1024.
4. The stated frequency must be externally applied to EXTAL only after the IMP has been placed in the lowest power mode
    with LPREC = 1. The 68000 core is not specified to operate at this frequency, but the rest of the IMP is. In this configuration,
    the user does not divide the clock internally using the LPCD4-LPCD0 bits in the system control register.


Description

The IMP TS68008 is a very large-scale integration (VLSI) device incorporating the main building blocks needed for the design of a wide variety of controllers. The device is especially suitable to applications in the communications industry. The IMP TS68008 is the first device to offer the benefits of a closely coupled, industry-standard, TS68000/TS68008 microprocessor core and a flexible communications architecture. This multichannel communications device may be configured to support a number of popular industry interfaces, including those for the integrated services digital network (ISDN) basic rate and terminal adapter applications. Through a combination of architectural and programmable features, concurrent operation of different protocols is easily achieved using the IMP. Data concentrators, line cards, bridges, and gateways are examples of suitable applications for this versatile device.

The IMP TS68008 is a high-density complementary metal-oxide semiconductor (HCMOS) device consisting of a TS68000/TS68008 microprocessor core, a system integration block (SIB), and a communications processor (CP). The TS68302 block diagram is shown in Figure 1.

Note: GCI is sometimes referred to as IOM2.
