Architectural Overview
The Z86D99 is a low-voltage general-purpose one-time programmable (OTP) Z8? microcontroller with an integrated four-channel 8-bit sigma delta analog-to-digital converter. The Z86L99 is the read-only memory (ROM) version of this controller.
Features
? Four-channel, 8-bit sigma delta analog-to-digital (A/D) converter with external
voltage references (not available in the 28-pin configuration)
? Two independent analog comparators
? Controlled current output
? 489 bytes of RAM
– 233 bytes of general-purpose register-based RAM
– 256 bytes of RAM mapped into the program memory space that can be
used as data RAM or executable RAM
? 32 Kbytes of OTP memory (Z86D99X)
? 16 Kbytes of ROM (Z86L99X)
Counter/Timers
? Special architecture to automate generation and reception of complex pulses
or signals:
– Programmable 8-bit counter/timer (T8) with two 8-bit capture registers and
two 8-bit load registers
– Programmable 16-bit counter/timer (T16) with one 16-bit capture register
pair and one 16-bit load register pair
– Programmable input glitch filter for pulse reception
? One general-purpose 8-bit counter/timer (T1) with 6-bit prescaler
Input/Output and Interrupts
? Thirty-two I/Os, twenty-nine of which are bidirectional I/Os with programmable
resistive pull-up transistors (24 I/Os are available in the 28-pin configuration)
? Sixteen I/Os are selectable as stop-mode recovery sources
? Six interrupt vectors with nine interrupt sources
– Three external sources
– Two comparator interrupts
– Three timer interrupts
– One low-battery detector flag
Operating Characteristics
? 8-MHz operation
? 3.0 V to 5.5 V operating voltage (Z86D990/Z86D991)
? 2.3 V to 5.5 V operating voltage (Z86L990/Z86L991)
? Low power consumption with three standby modes:
– Stop
– Halt
– Low Voltage Standby
? Low-battery detection flag
? Low-voltage protection circuit (also known as VBO, or voltage brownout,
circuit)
? Watch-dog timer and power-on reset circuits
User-Programmable Option Bits
? Clock source—RC/other (LC, resonator, or crystal)
? Watch-dog timer permanently enable
? 32-kHz crystal
? Port 20–27 pull-up resistive transistor
? Port 40–42 pull-up resistive transistor
? Port 44–47 pull-up resistive transistor
? Port 50–51 pull-up resistive transistor
? Port 54–57 pull-up resistive transistor
? Port 60–63 pull-up resistive transistor (not available in Z86D991/Z86L991)
? Port 64–67 pull-up resistive transistor (not available in Z86D991/Z86L991)
? P43 high impedance in STOP mode (available in OTP only)
Force P43 to output a 1 in the open-drain configuration
