Product Summary
The MC68B40CP is a programmable timer module. The MC68B40CP is a subsystem component of the M6800 family designed to provide variable system time intervals. The MC68B40CP has three 16-bit binary counters, three corresponding control registers, and a status register. These counters are under software control and may be used to cause system interrupts and or generate output signals.
Parametrics
MC68B40CP absolute maximum ratings: (1)supply voltage: -0.3 to +7.0 V; (2)input voltage: -0.3 to +7.0 V; (3)operating temperature range - TL to TH: 0 to +70 ℃; (4)storage temperature range: -55 to +150 ℃.
Features
MC68B40CP features: (1)operates from a single 5 V power supply; (2)fully TTL compatible; (3)single system clock required; (4)selectable prescaler on time 3 capable of 4 MHz for the MC6840, 6 MHz for the MC68A40 and 8 MHz for the MC68B40; (5)programmable interrupts output to MPU; (6)readable down counter indicates counts to go until time-out; (7)selectable gating for frequency or pulse-width comparision.
