Z86C95

CMOS Z8^®DIGITAL

SIGNAL PROCESSOR (DSP)

GENERAL DESCRIPTION

The Z86C95 MCU (Microcontroller Unit ) introduces a new

level of sophistication to Superintegration™ ICs. The

Z86C95 is a member of the Z8^®single-chip microcontroller

family incorporating a CMOS ROMless Z8 microcontroller

with an embedded DSP processorfordigitalservo control.

The DSP slave processor can perform 16-bit x 16-bit

multiplicates and accumulates in one clock cycle. Addi-

tionally, the Z86C95 is further enhanced with a hardwired

16-bitx16-bit multiplier and a 32-bit/16-bit divider, three

16-bit counter timers with capture and compare registers,

a half flash 8-channel 8-bit A/D converter with a 2 µsec

conversion time, an 8-bit DAC with 1/4 programmable gain

stage, UART, serial peripheral interface, and a PWM

output channel (Functional Block Diagram). It is fabricated

using CMOS technology and offered in an 80-pin QFP, 84-

pin PLCC, or 100-pin VQFP package.

There are 256 registers located on chip and organized as

236 general-purpose registers, 16 control and status reg-

isters, and four I/O port registers. The register file can be

divided into sixteen groups of 16 working registers each.

Configuration of the registers in this manner allows the use

of short format instructions; in addition, any of the indi-

vidualregisters can be accessed directly. Also, the Z86C95

contains 512 bytes of DSP Program RAM and 128 words

of DSP data RAM.

Notes:

All Signals with a preceding front slash, "/", are active Low, e.g.:

B//W (WORD is active Low); /B/W (BYTE is active Low, only).

Power connections follow conventional descriptions below:

The Z86C95 provides up to 16 output address lines thus

permitting an address space ofup to 64 Kbytes ofdata and

program memory each. Eight address outputs (AD7-AD0)

are provided by a multiplexed, 8-bit, Address/Data bus.

The remaining 8 bits are provided via output address bits

A15-A8.

OPERATING ERRATA

This notice only applies to devices top marked "Z86C9524

ASC/FSC/VSC" with a date code of 9237 or later.

The following operating errata only applies to devices

topmarked with "Z86C95 ASC/FSC/VSC."

1. A DSP load to the DAC Register fails below approxi-

mately V_CC= 4.7V.

1. ICC1 at HALT Mode will show a current of 17-18 mA,

then will jump to 40-70 mA, and will settle between 17-

24 mA. Settling time is about 10-15 seconds.

2. Clipping occurs in the linearity of the DAC with a 100K

load at about 3.3V output (VDHI = 3.5V).

2. ICC2 at STOP Mode and DSP Pause will show a

current of 1-2 mA, then will jump to 5-7 mA, and will

settle at 3-4 mA. Settling time is about 10-15 seconds.

3. I_CC1 at HALT Mode will show a current of 17-18 mA,

then will jump to 40-70 mA, and will settle between 17-

24 mA. Settling time is about 10-15 seconds.

The following operating errata only applies to devices

topmarked with "Z86C9540 ASC/FSC/VSC or SL 1636."

4. I_CC2 at STOP Mode and DSP Pause will show a current

of 1-2 mA, then will jump to 5-7 mA, and will settle at 3-

4 mA. Settling time is about 10-15 seconds.

1. ICC1 at HALT Mode will show a current of 17-18 mA,

then will jump to 40-70 mA, and will settle between 17-

24 mA. Settling time is about 10-15 seconds.
