10 / 67 page SM59R16A2/SM59R08A2 8-Bit Micro-controller 64KB/32KB ISP Flash & 2KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. ISSFD-M034 10 Ver.B SM59R16A2/SM59R08A2 06/2009 Function Description 1 General Features SM59R16A2/SM59R08A2 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 Embedded Flash The program can be loaded into the embedded 64KB/32KB Flash memory via its writer or In-System Programming (ISP).The high-quality Flash has a 100K-write cycle life, suitable for re-programming and data recording as EEPROM. 1.2 IO Pads 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 ~ P5 are designed with internal pull-up resistors. The IO pad structure is given below: Fig. 1-1: IO pad structure All the pads for P0 ~ P5 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. The IO pads can withstand 4KV ESD in human body mode guaranteeing the SM59R16A2/SM59R08A2’s quality in high electro-static environments. 1.3 2T/1T Selection The conventional 52-series MCUs are 12T, i.e., 12 oscillator clocks per machine cycle. SM59R16A2/SM59R08A2 is a 2T or 1T MCU, i.e., its machine cycle is two-clock or one-clock. In the other words, it can execute one instruction within two clocks or only one clock. The difference between 2T mode and 1T mode are given in the example in Fig. 1-2. |
