6.2.4.Power manager

This block includes the 5.0 V-to-3.3 V regulator and power source selection.

6.2.5.Audio interface

This block provides stereo audio line IN interface and microphone (with pre-amp) OUT interface. Its main purpose is to demonstrate the carkit application (play audio or voice with carkit).

7. Connector pin information

7.1.DB-25 PC parallel port connector (J10) pin assignment

J10 is used to connect to the PC parallel port through the DB-25 printer cable. Table 7-1 shows its pin assignment.

Table 7-1: DB-25 PC parallel port connector (J10) pin assignment

Pin no	Printer port signal	ISP1301 evaluation board signal
9	D7	SDAOUT#
11	S7#	SDAIN#
15	S3	SCLIN
17	C3#	SCLOUT#
10,13,18–25	—	GND
1–8,12,14,16,	—	No connection

7.2.8-bit microprocessor interface 20 x 2 header (J13) pin assignment

J13 is used to connect to a generic 8-bit parallel bus microprocessor controller. The bus uses the Intel® mode. Required signals include D0–D7, A0, WR_N, RD_N, CS_N, INT1 and INT2. Table 7-2 shows the pin assignment for J13.

Note: We use a 20 x 2 header to make it compatible with the Philips ISP1362 and ISP1161x ISA interface boards.

Table 7-2: 8-bit microprocessor-interface 20 x 2 header (J13) pin assignment[1]

Pin no	Pin name	Pin no	Pin name	Pin no	Pin name	Pin no	Pin name
1	GND	11	n. c.	21	D7	31	D2
2	n. c.	12	+3.3 V	22	INT2	32	n. c.
3	n. c.	13	n. c.	23	D6	33	D1
4	CHRG_EN	14	n. c.	24	INT1	34	WR_N
5	n. c.	15	n. c.	25	D5	35	D0
6	n. c.	16	+5.0 V	26	n. c.	36	RD_N
7	n. c.	17	n. c.	27	D4	37	n. c.
8	n. c.	18	+5.0 V	28	n. c.	38	CS_N
9	n. c.	19	GND	29	D3	39	A0
10	+3.3 V	20	n. c.	30	n. c.	40	n. c.

[1] n. c.—Denotes no connection.

Note: An external OTG Controller system can use the CHRG_EN signal to enable or disable +5.0 V from the VBUS line of the mini-AB connector to pin 2 of J2. This is useful when an analog audio carkit is attached and the carkit can charge the external battery.

7.3.USB OTG Controller interface 8 x 2 header (J8 and J3) pin assignment

Header connectors J8 and J3 are used to connect the ISP1301 to the OTG Controller core. J8 includes the USB Serial Interface Engine (SIE) signals—DAT_VP, SE0_VM, RCV and OE_TP_INT_N—and I2C signals—SDA, SCL and INT_N. J3 also includes other signals that may be used by selected OTG Controller.
