Function Description
1
SM59D03G2 is an 8-bit micro-controller. All of its functions and the detailed meanings of SFR will
be given in the following sections.
1.1
The program can be loaded into the embedded 8K bytes Flash memory via its writer or ISP
(In-System Programming) or ICP (In-Circuit Programming) function.
The high-quality Flash is suitable for re-programming and data recording as EEPROM.
1.2
The IO pads are compatible to the 8052 series. P0 is open-drain in the input or output high
condition, so the external pull-up resistor is required. P1 ~ P4 are designed with internal pull-up
resistors. The IO pad structure is given below:
All the pads for P0 ~ P4 are with slew rate to reduce EMI. The other way to reduce EMI is to disable
the ALE output if unused. This is selected by its SFR. In 3.3V applications, the IO pads are 5V
tolerant except for XATL1 and XTAL2.
