8-BIT MCU WITH UP TO 16K FLASH MEMORY, 10-BIT ADC, TWO 16-BIT TIMERS, TWO I2C, SPI, SCI

STMicroelectronics 

ST72340, ST72344, ST72345

3 REGISTER & MEMORY MAP

As shown in Figure 5, the MCU is capable of ad-

dressing 64 Kbytes of memories and I/O registers.

The available memory locations consist of 128

bytes of register locations, up to 1 Kbytes of RAM,

256 bytes of Data EEPROM and up to 16 Kbytes

Figure 5. Memory Map

of user program memory. The RAM space in-

cludes up to 256 bytes for the stack from 0100h to

01FFh.

The highest address bytes contain the user reset

and interrupt vectors.
