Description
The SM59D03G2 series product is an 8-bit single chip
macro-controller with 8K bytes Flash & 1K byte RAM
embedded.
It is a derivative of the 8052 micro-controller family with a
fully compatible instruction sets.
The 8K bytes embedded Flash can be programmed via a
commercial writer or ISP (In-System Programming) or ICP
(In-Circuit Programming) function. The unused Flash on 4K
bytes ISP service Program area can be the memory space
for the EEPROM application through the ISP.
After programming, the code can be protected to prevent
illegal read and write.
Its plentiful peripherals can make many applications easier
and more efficient, such as dual DPTR, UART, WDT,
Timers, PCA and EEI which are functionally compatible
with most other chips.
SM59D03G2 also provides power saving modes (IDLE and
STOP), low EMI characteristics, etc. All of the
requirements are considered to achieve the ideal MCU.
