	No.	Symbol	I/O	Explain
	1	AMANT	I	AM antenna input	AM antenna input high impedance AMANT pin is connected with
					an all antenna by way of 4.7∝ H. (LAU type inductor) A series circuit
					including an inductor and a resistor is connected with RF ground for
					the countermeasure against the ham of power transmission line.
	2	RFGND		RF ground	Ground of antenna block
	3	FMANT	I	FM antenna input	Input of FM antenna 75Ω Surge absorber(DSP-201M-S00B)is necessary.
D	4	VCC		power supply	The power supply for analog block. D.C 8.4V ± 0.3V
	5	SL	O	signal level	Output of FM/AM signals level
	6	CE2	I	chip enable-2	Chip enable for EEPROM ” Low” active
	7	WC	I	write control	You can write EEPROM, when EEPROM write control is “ Low” .
					Ordinary non connection
	8	CE1	I	chip enable-1	Chip enable for AF•RF ” High” active
	9	CK	I	clock	Clock
	10	DI	I	data in	Data input
	11	NC		non connection	Not used
	12	OSCGND		osc ground	Ground of oscillator block
	13	ROM_VDD		power supply	Power supply for EEPROM pin 13 is connected with a power supply of
					micro computer.
E	14	DO	O	data out	Data output
	15	DGND		digital ground	Ground of digital block
	16	NC		non connection	Not used
	17	VDD_3.3		power supply	The power supply for digital block. 3.3V ± 0.2V
	18	NC		non connection	Not used
	19	NC		non connection	Not used
	20	NC		non connection	Not used
	21	NC		non connection	Not used
	22	AUDIOGND		audio ground	Ground of audio block
	23	L ch	O	L channel output	FM stereo “ L-ch” signal output or AM audio output
	24	R ch	O	R channel output	FM stereo “ R-ch” signal output or AM audio output
