Notes: 1. The halt mode current is measured with the CPU executing 20 instructions every 125 ms. 2. The VSENSE voltage When the VDD voltage falls, the VSENSE flag is set at the point that voltage falls under 1.75 V (typical). The TST instruction can be used to read the value of the VSENSE flag. Applications can easily determine when the batteries are exhausted by monitoring this flag. After VSENSE is set when the supply voltage falls, it will not be reset if the supply voltage rises by less than 0.1 V, because the voltages detected by the VSENSE circuit differ when the supply voltage is falling and when the supply voltage is rising.

PA0 PA1 PA2 PA3 I
Special-purpose key return signal input ports designed with a low threshold voltage. When used in conjunction with port PB to form a key matrix, up to 3 simultaneous key presses can be detected. The four pull-down resistors are selected together in a single operation using the IOS instruction (PWn = 2, b1); they cannot be specified individually. Input is disabled in backup mode, and the pull-down resistors are disabled after a reset.

PB3 PB2 PB1 PB0 O
Special-purpose key source signal output ports. Since unbalanced CMOS output transistor circuits are used, diodes to prevent short-circuits when multiple keys are pressed are not required. These ports go to the output high-impedance state in backup mode. These ports go to the output high-impedance state after a reset and remain in that state until an output instruction (OUT, SPB, or RPB) is executed. Care is required in designing the output loads if these pins are used for functions other than key source outputs.

PC0 PC1 PC2 PC3 INT/PD0 PD1 PD2 PD3 General-purpose output ports with shared beep tone output function (PE0 only). The BEEP instruction is used to switch PE0 between the general-purpose output port and beep tone output functions. To use PE0 as a general-purpose output port, execute a BEEP instruction with b2 set to 0. Set b2 to 1 to use PE0 as the beep tone output port. The b0 and b1 bits are used to select the beep tone frequency. There are two beep tone frequencies supported. I/O General-purpose I/O ports*. PD0 can be used as an external interrupt port. Input or output mode can be set in a bit unit using the IOS instruction (Pwn = 4, 5). A value of 0 specifies input, and 1 specifies output. These ports go to the input disabled highimpedance state in backup mode. They are set to function as general-purpose input ports after a reset.

BEEP/PE0 PE1
When PE0 is set up as the beep tone output, executing an output instruction to PN0 only changes the state of the internal output latch, it does not affect the beep tone output in any way. Only the PE0 pin can be switched between the general-purpose output function and the beep tone output function; the PE1 pin only functions as a generalpurpose output. These pins go to the high-impedance state in backup mode and remain in that state until an output instruction or a BEEP instruction is executed. Since these ports are open-drain ports, resistors must be inserted between these pins and VDD. These ports are set to their general-purpose output port function after a reset. General-purpose input and A/D converter input shared function ports (PF2 is a generalpurpose input only port). The IOS instruction (Pwn = FH) is used to switch between the general-purpose input and A/D converter port functions. The general-purpose input and A/D converter port functions can be switched in a bit unit, with 0 specifying generalpurpose input, and 1 specifying the A/D converter input function. To select the A/D converter function, set up the A/D converter pin with an IOS instruction with Pwn set to 1. The A/D converter is started with the UCC instruction (b3 = 1, b2 = 1). The ADCE flag is set when the conversion completes. The INR instruction is used to read in the data. If an input instruction is executed for one of these pins which is set up for analog input, the read in data will be at the low level since CMOS input is disabled. In backup mode these pins go to the input disabled high-impedance state. These ports are set to their general-purpose input port function after a reset. The A/D converter is a 5-bit successive approximation type converter, and features a conversion time of 1.28 ms. Note that the full-scale A/D converter voltage (1FH) is (63 * 96)VDD.

The IOS instruction is used for switching both between the segment output and general-purpose I/O functions and between input and output for the general-purpose I/O port function.* * When used as segment output ports The general-purpose I/O port function is selected with the IOS instruction (Pwn = 8). 25 26 27 28 PG3/S20 PG2/S19 PG1/S18 PG0/S17 I/O 29 30 31 32 PH3/S16 PH2/S15 PH1/S14 PH0/S13 b0 = S17 to 20/PG0 to 3 (0: Segment output, 1: PG0 to 3) The general-purpose I/O port function is selected with the IOS instruction (Pwn = 9). b0 = S13 to 16/PH0 to 3 (0: Segment output, 1: PH0 to 3) * When used as general-purpose I/O ports The IOS instruction (Pwn = 6,7) is used to select input or output.

In backup mode, these pins go to the input disabled, high-impedance state if set up as general-purpose outputs, and are fixed at the low level if set up as segment outputs. These ports are set up as segment outputs after a reset. Although the general-purpose port/LCD port setting is a mask option, the IOS instruction must be used as described above to set up the port function.

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any or all SANYO products (including technical data, services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be exported without obtaining the export license from the authorities concerned in accordance with the above law.

Any and all information described or contained herein are subject to change without notice due to product/technology improvement, etc. When designing equipment, refer to the "Delivery Specification" for the SANYO product that you intend to use. Information (including circuit diagrams and circuit parameters) herein is for example only; it is not guaranteed for volume production. SANYO believes information herein is accurate and reliable, but no guarantees are made or implied regarding its use or any infringements of intellectual property rights or other rights of third parties.
