**HT21 386SX/286 Single Chip (20 MHz) c:Aug91
***Info:
The HT21 is an advanced PC/AT compatible, single-chip 80386SX/80286
design solution. This highly integrated single chip allows simple,
low cost system design options while featuring high performance, low
power consumption, and minimum board space requirements. Advanced
memory management features include support for page mode, 2 or 4-way
interleaving in both pipelined and non-pipelined modes. The LIM 4.0
hardware implementation features dual sets of 32 registers with full
context support for highest performance Optimization of extended local
memory accesses. An advanced EMS hardware write-protect option is
provided. The HT21 supports 256K and 1M DRAMs in l by 1, 1 by 4, and 1
by 9 device configurations for up to 8MB of on-board system memory. A
flexible Shadow RAM option for System and Video BIOS as well as 8-
16-bit BIOS Options adds to overall design versatility.
A complete PC/AT compatible system with advanced features may be
implemented with minimal external support logic. The HT21 performs all
CPU and peripheral support functions in a single chip. Integrated
device functions include DMA Controllers, a Memory Mapper, Timers,
Counters, Interrupt Controllers, a Bus Controller and all supporting
circuitry for PC core logic requirements. The chip also contains all
the necessary address buffers, data transceivers, memory drivers,
parity checking and supporting circuitry for a complete high
performance computer solution. An asynchronous AT Bus clock allows for
a constant 8MHz Bus clock rate for highest bus device compatibility as
defined in IEEE Spec P996. In controlled bus applications the HT21
supports up to a 12 MHz Bus Clock rate. This device is packaged in a
208-pin Plastic Quad Flat Pack combining several external buffers into
this space saving solution.
