AT87C5103 帶有12K系統(tǒng)內(nèi)可編程ROM/OTP存儲器

AT87C5103 概述

The AT8xC5103 is a high-performance ROM/OTP version of the 80C51 8-bit Microcontroller in 16 and 24-pin packages.
The AT8xC5103 contains a standard C51 CPU core with 12 Kbytes ROM/OTP program memory, 256 bytes of internal RAM, 256 bytes of extended internal RAM, a 5- sources 4-level interrupt system, two timer/counters and a SPI serial bus controller. The AT8xC5103 is also dedicated for analog interfacing applications. For this, it has a five channels Programmable Counter Array.
In addition, the AT8xC5103 implements the X2 speed improvement mechanism. The X2 feature allows to keep the same CPU power at a divided by two oscillator frequency.
The fully static design of the AT8xC5103 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data.
