Description  
AT89LS53  
The AT89LS53 is a low-power, wide-voltage range, high-performance CMOS 8-bit  
microcomputer with 12K bytes of downloadable Flash programmable and erasable  
read only memory. The device is manufactured using Atmel’s high density nonvolatile  
memory technology and is compatible with the industry standard 80C51 instruction  
set and pinout. The on-chip downloadable Flash allows the program memory to be  
reprogrammed in-system through an SPI serial interface or by a conventional nonvol-  
atile memory programmer. By combining a versatile 8-bit CPU with downloadable  
Flash on a monolithic chip, the Atmel AT89LS53 is a powerful microcomputer which  
provides a highly flexible and cost effective solution to many embedded control appli-  
cations.  
Not Recommended  
for New Designs.  
Use AT89S8253.  
The AT89LS53 provides the following standard features: 12K bytes of downloadable  
Flash, 256 bytes of RAM, 32 I/O lines, programmable watchdog timer, two Data Point-  
ers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full  
duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89LS53 is  
designed with static logic for operation down to zero frequency and supports two soft-  
ware selectable power saving modes. The Idle Mode stops the CPU while allowing  
the RAM, timer/counters, serial port, and interrupt system to continue functioning. The  
Power Down Mode saves the RAM contents but freezes the oscillator, disabling all  
other chip functions until the next interrupt or hardware reset.  
The downloadable Flash can be changed a single byte at a time and is accessible  
through the SPI serial interface. Holding RESET active forces the SPI bus into a serial  
programming interface and allows the program memory to be written to or read from  
unless Lock Bit 2 has been activated.
