6532 (MEMORY, 110, TIMER ARRAY)
THE 8532 CONCEPT-
The 6532 Is designed to operate In conjunction with the MCS650X Microprocessor Family. It is
comprised of a 128 x 8 static RAM, two software controlled 8 bit bl-dlrectional data ports allowing
direct Interfacing between the microprocessor unit and peripheral devices, a software programmable
Interval timer with Interrupt capable of timing In various Intervals from 1 to 262,144 clock periods, and
a programmable edge detect circuit.
FEATURES OF THE 8532
• 8 bit bl-dlrectlonal Data Bus for direct
communication with the microprocessor
• Programmable edge-sensitive Interrupt
• 128 x 8 static RAM
• Two 8 bit bl-dlrectlonal data ports for
Interface to peripherals
• Two programmable 110 Peripheral Data
Direction Registers
• Programmable Interval Timer
• Programmable Interval Timer Interrupt
• TTL & CMOS compatible. peripheral lines
• Peripheral pins with Direct Transistor
Drive Capability
• High Impedance Three-State Data Pins
• 1MHz, 2MHz and 3MHz operation
