CUSTOMER PROCUREMENT SPECIFICATION
Z86C95
CMOS Z8(R) DIGITAL SIGNAL PROCESSOR (DSP)
GENERAL DESCRIPTION
The Z86C95 MCU (Microcontroller Unit ) introduces a new level of sophistication to SuperintegrationTM ICs. The Z86C95 is a member of the Z8(R) single-chip microcontroller family incorporating a CMOS ROMless Z8 microcontroller with an embedded DSP processor for digital servo control. The DSP slave processor can perform 16-bit x 16-bit multiplicates and accumulates in one clock cycle. Additionally, 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 sec 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, 84pin PLCC, or 100-pin VQFP package. The Z86C95 provides up to 16 output address lines thus permitting an address space of up to 64 Kbytes of data 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. There are 256 registers located on chip and organized as 236 general-purpose registers, 16 control and status registers, 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 individual registers 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: Connection Power Ground Circuit VCC GND Device VDD VSS
OPERATING ERRATA
This notice only applies to devices top marked "Z86C9524 ASC/FSC/VSC" with a date code of 9237 or later. 1. A DSP load to the DAC Register fails below approximately VCC = 4.7V. 2. Clipping occurs in the linearity of the DAC with a 100K load at about 3.3V output (VDHI = 3.5V). 3. ICC1 at HALT Mode will show a current of 17-18 mA, then will jump to 40-70 mA, and will settle between 1724 mA. Settling time is about 10-15 seconds. 4. 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 34 mA. Settling time is about 10-15 seconds. The following operating errata only applies to devices topmarked with "Z86C95 ASC/FSC/VSC." 1. ICC1 at HALT Mode will show a current of 17-18 mA, then will jump to 40-70 mA, and will settle between 1724 mA. Settling time is about 10-15 seconds. 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. The following operating errata only applies to devices topmarked with "Z86C9540 ASC/FSC/VSC or SL 1636." 1. ICC1 at HALT Mode will show a current of 17-18 mA, then will jump to 40-70 mA, and will settle between 1724 mA. Settling time is about 10-15 seconds.
