Oscillation input pin on the OSC side: Connect to a quartz oscillator (ceramic resonator), or input external clock. Oscillation output pin on the OSC side: Connect to a quartz oscillator (ceramic resonator). When external clock is input to the OSC0 pin, the OSC1 pin should be kept open. System reset input: When this pin is set to the "L" level, the internal status is initialized to start execution of instructions from address 0040H. The input is pulled up to VDD with an internal pull-up resistor.

8-bit input-output port (port 0): Each of bits 0 to 7 can be configured to be an input or an output by the direction register of port 0 (P0DIR). In addition to the basic function as an input-output port, a secondary function is allocated to each of P0.0 through P0.7. Refer to the next table. 3-bit input-output port (port 1): Each of bits 1.2 to 1.4 is configured to be input or output by the direction register of port 1 (P1DIR). In addition to the basic function as an input-output port, a secondary function is allocated to each of P1.2 through P1.4. Refer to "PIN DESCRIPTION (Secondary Function)". 6-bit input port (port 3): Each of P3.0 to P3.5 functions as analog input channel of A/D converter. 8-bit input-output port (port 4): 8-bit input-output port. 7-bit input-output port (port 5): Each of bits 5.0 to 5.6 can be configured to be an input or an output by the direction register of port 5 (P5DI). 1-bit input port (port 6.0): 1-bit input port. 1-bit output port (port 6.1): Pulled high when reset is done. If this pin is set to the "0" level during reset, this IC goes into a test mode, disabling execution of the user program. 6-bit input-output port (port 6): 6-bit input-output port. 8-bit input-output port (port 7): Each of bits 7.0 to 7.7 can be configured to be an input or an output by the direction register of port 7 (P7DIR).

Definition of Terms Resolution Recognizable minimum input analog value. This can be resolved into 28 = 256, that is AVDD / 256 in 8 bits. Deviation between ideal conversion characteristics as an 8-bit A/D converter and actual conversion characteristics. (Not including quantization error.) Ideal conversion characteristics means a step which divides voltage between VRH and LRL into 256. Smoothness of conversion characteristics. 1LSB = AVDD / 256 is ideal for analog input voltage width corresponding to change per 1 bit of digital output. Deviation between the ideal bit size and bit size at arbitrary point in conversion range. Deviation between ideal conversion characteristics of transfer point for digital outputs "000H" to "001H" and actual conversion characteristics. Deviation between ideal conversion characteristics of transfer point for digital outputs "0FEH" to "0FFH" and actual conversion characteristics.

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
