Familiarity with ESA 31 micro controller kit:
Main features of ESA 31 (8031 based): ESA 31 can be operated either from onboard keyboard or from a CRT terminal through its RS 232-C interface. Keyboard and serial monitor programs support the entry of users program, editing, debug facilities like breakpoints, single stepping & full execution of user programs. 1-pass Assembler can assemble any memory resident assembly language program. 1-pass Dis-assembler disassembles the object code into standard INTEL mnemonics. Total of 120KB memory is provided of which 64KB of memory is program memory and 56KB of memory is data memory. The monitor of the trainer occupies 32KB out of 64KB of program memory. Standard bus compatible signals available on the bus connector for easy expansion. SPECIFICATIONS: Microcontroller: 8031/8051 operated at 11.0592 MHz Memory follows: : Four 28-pin JEDEC sockets offer 120KB of memory as

32KB of firmware in one 27256 (Program memory) 32KB of SRAM using one 62256 (User program memory) 56KB of SRAM as data memory using two 62256s. 5

The memory map is as follows: DEVICE 27256 62256 62256 62256 ADDRESS RANGE...
