SM89516A 8-Bits Micro-controller With 64KB flash & 1KB RAM embedded Extension Function Description 1. Memory Structure The SM89516A is the general 8052 hardware core as a single chip micro controller. Its memory structure follows general 8052 structure. 1.1 Program Memory The SM89516A has 64K byte on-chip flash memory which used as general program memory. The address range for the 16K byte is $0000 to $FFFF. Note: The single flash block address structure for doing as well as program ROM flash. 1.2 Data Memory The SM89516A has 1K bytes on-chip RAM, 256 bytes of it are the same as general 8052 internal memory structure while the expanded 768 bytes on-chip RAM can be accessed by external memory addressing method (by instruction MOVX).

When system reset by Watch Dog Timer overflow. WDR will be set to 1, The bit 7 (WDR) of SCONF is Watch Dog Timer Reset bit. It will be set to 1 when reset signal generated by WDT overflow. User should check WDR bit whenever un-predicted reset happened. OME : 768 bytes on-chip RAM enable bit. The bit 1 (OME) of SCONF can enable or disable the on-chip expanded 768 byte RAM. The default setting of OME bit is 0 (disable). ALEI : ALE output inhibit bit, to reduce EMI. Setting bit 0 (ALEI) of SCONF can inhibit the clock signal in Fosc/6Hz output to the ALE pin. 1.3 I/O Pin Configuration The ports 1, 2 and 3 of standard 8051 have internal pull-up resistor, and port 0 has open-drain outputs. Each I/O pin can be used independently as an input or an output. For I/O ports to be used as an input pin, the port bit latch must contain a ‘1’ which turns off the output driver FET. Then for port 1, 2 and 3 port pin is pulled high by a weak internal pull-up, and can be pulled low by an external source. The port 0 has open-drain outputs which means its pull-ups are not active during normal port operation. Writing ‘1’ to the port 0 bit latch will causing bit floating so that it can be used as a high-impedance input. The port 4 used as GPIO will has the same function as port 1, 2 and 3.

SM89516A 8-Bits Micro-controller With 64KB flash & 1KB RAM embedded 3.Watch Dog Timer The Watch Dog Timer (WDT) is a 16-bit free-running counter that generate reset signal if the counter overflows. The WDT is useful for systems which are susceptible to noise, power glitches, or electronics discharge which causing software dead loop or runaway. The WDT function can help user software recover from abnormal software condition. The WDT is different from Timer0, Timer1 and Timer2 of general 8052. To prevent a WDT reset can be done by software periodically clearing the WDT counter. User should check WDR bit of SCONF register whenever un-predicted reset happened The purpose of the secure procedure is to prevent the WDTC value from being changed when system runaway. There is a 250KHz RC oscillator embedded in chip. Set WDTE = “1” will enable the RC oscillator and the frequency is independent to the system frequency. To enable the WDT is done by setting 1 to the bit 7 (WDTE) of WDTC. After WDTE set to 1, the 16-bit counter starts to count with the RC oscillator. It will generate a reset signal when overflows. The WDTE bit will be cleared to 0 automatically when SM8958A been reset, either hardware reset or WDT reset. To reset the WDT is done by setting 1 to the CLEAR bit of WDTC before the counter overflow. This will clear the content of the 16-bit counter and let the counter re-start to count from the beginning. 3.1 Watch Dog Timer Registers: Watch Dog Timer Registers - WDT Control Register (WDTC, $9F) bit-7 WDTE R Clear Unused Unused PS2 PS1 bit-0 PS0 Read / Write: R/W - R/W - - R/W R/W R/W Reset value: 0 * 0 * * 0 0 0 WDTE : Watch Dog Timer enable bit CLEAR : Watch Dog Timer reset bit PS[2:0] : Overflow period select bits PS [2:0] Overflow Period (ms) 000 16.384 001 32.768 010 65.536 011 131.072 100 262.144 101 524.288 110 1048.576 111 2097.152 Specifications subject to change without notice contact your sales representatives for the most recent information.

Reduce EMI Function The SM89516A allows user to reduce the EMI emission by setting 1 to the bit 0 (ALEI) of SCONF register. This function will inhibit the clock signal in Fosc/6Hz output to the ALE pin. 5. Specific Pulse Width Modulation (SPWM) The Specific Pulse Width Modulation (SPWM) module contain 1 kind of PWM sub module: SPWM (Specific PWM). SPWM has five 8-bit channels. 5.1 SPWM Function Description: The 8-bit SPWM channel is composed of an 8-bit register which contains a 5-bit SPWM in MSB portion and a 3-bit binary rate multiplier (BRM) in LSB portion. The value programmed in the 5-bit SPWM portion will determine the pulse length of the output. The 3-bit BRM portion will generate and insert certain narrow pulses among an 8-SPWM-cycle frame. The number of pulses generated is equal to the number programmed in the 3-bit BRM portion. The usage of the BRM is to generate equivalent 8-bit resolution SPWM type DAC with reasonably high repetition rate through 5-bit SPWM clock speed. The SPFS[1:0] settings of SPWMC ($A3) register are dividend of Fosc to be SPWM clock, Fosc/2^(SPFS[1:0]+1). The SPWM output cycle frame repetition rate (frequency) equals (SPWM clock)/32 which is [Fosc/2^(SPFS[1:0]+1)]/32.
