Description

The Z89135/136 is a fully integrated, dual processor controller 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 an 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 converter with up to 128 kHz sample rate and 10-bit PWM D/A converter. The sampling rates for the converters are programmable. The precision of the 8-bit A/D may be extended by resampling the data at a lower rate in software.

The Z8 and DSP processors are coupled by mailbox registers and an interrupt system, which allows DSP or Z8 programs 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 always the internal ROM.
