Ürün Açıklaması

MCCS146818B1M MCCS146818BM real time clocks plus RAM, both with crystal lithium cell (real time clock modules RTCMs).These devices include unique MOTEL concept with both Motorola Intel microprocessor timing cycles. These devices combine five important features: complete time-of-day clock with alarm hundred year calendar, programmable interrupt alarm timing functions, square wave generation circuit, bytes ultra power static RAM, external parts. MCCS146818B1M MCCS146818BM interface with 1-MHz processor buses while consuming very little power, allowing battery last long period time.
only difference between these RTCMs that MCCS146818B1M added feature being able clear (set $FF) built-in general-purpose placing jumper RCLR Vgg. This feature available MCCS146818BM device.
