Product Summary
The TMS9900NL is a programmable system interface, multifunctioned component designed to provide low cost interrupts and I/O ports in a 9900/9980 microprocessor system. It is fabricated with N channel silicon-gate technology and is completely TTL compatible on all inputs including the power supply (+5V) and single-phase clock. The programmable system interface provides a 9900/9980 system with interrupt control, I/O ports, and a real-time clock shown in figure 1.
Parametrics
TMS9900NL absolute maximum ratings: (1)Supply voltage, VCC and VSS: -0.3 V to 10 V; (2)All input and output voltages: -0.3 V to 10 V; (3)Continuous power disspation: 0.75W; (4)Operating free-air temperature range: 0℃ to 70℃; (5)Storage temperature range: - 65℃ to 150℃.
Features
TMS9900NL features: (1)N-channel Silicon-gate process; (2)9900 series CRU peripheral; (3)Performs interrupt and I/O interface functions: 6 dedicated interrupt input lines; 7 dedicated I/O ports; 9 ports programmable as interrupts or I/O; (4)Easily stacked for interrupt and I/O expansion; (5)Interval and event timer; (6)Single 5V supply.
