GENERAL DESCRIPTION
The Z89135/136 is a fully integrated, dual processor con-
troller designed for low-cost digital telephone answering
machines. The I/O control processor is a Z8® MCU with 24
KB of program memory, two 8-bit counter/timers, and up to
47 I/O pins. The DSP is a 16-bit processor with a 24-bit
ALU and accumulator, 512 x 16 bits of RAM, single cycle
instructions, and 6K word program ROM plus constants
memory. The chip also contains a half-flash 8-bit A/D con-
verter with up to 128 kHz sample rate and 10-bit PWM D/A
converter. The sampling rates for the converters are pro-
grammable. The precision of the 8-bit A/D may be extend-
ed by resampling the data at a lower rate in software.
The Z8 and DSP processors are coupled by mailbox regis-
ters and an interrupt system, which allows DSP or Z8 pro-
grams to be directed by events in each other’s domain.
The Z89136 is the ROMless version of the Z89135. The
DSP is not ROMless. The DSP's program memory is al-
ways the internal ROM.
