Pin #

Name

Type

Description

SPI MOSI: When the device is configured as a SPI slave, an external SPI

master sends commands, addresses and data to the device on MOSI. When

the device is configured as a SPI master (ZL30260, ZL30262 only), the

device sends commands, addresses and data on MOSI to an external SPI

EEPROM during auto-configuration.

VDDL

Lower Core Power Supply. 1.8V

5% or same voltage as VDDH.

VDDIO

Digital Power Supply for Non-Clock I/O Pins. 1.8V to VDDH.

VDDOA

Power Supply for OC1P/N and OC2P/N. 1.5V to VDDH.

VDDOB

Power Supply for OC3P/N. 1.5V to VDDH.

VDDOC

Power Supply for OC4P/N and OC5P/N. 1.5V to VDDH.

VDDOD

Power Supply for OC6P/N and OC7P/N. 1.5V to VDDH.

VDDOE

Power Supply for OC8P/N. 1.5V to VDDH.

VDDOF

Power Supply for OC9P/N and OC10P/N. 1.5V to VDDH.

E-pad

Ground. 0 Volts.

Important Note: The voltages on VDDL, VDDIO, and all VDDOx pins must not exceed VDDH. Not complying with

this requirement may damage the device.

5. Functional Description

5.1

Device Identification

The 12-bit read-only ID field and the 4-bit revision field are found in the ID1 and ID2 registers. Contact the factory to

interpret the revision value and determine the latest revision.

5.2

Pin-Controlled Automatic Configuration at Reset

The device configuration is determined at reset (i.e. on the rising edge of RSTN) by the signal levels on these device

pins: TEST/GPIO3, AC2/GPIO2, AC1/GPIO1, AC0/GPIO0, IF1/MISO and IF0/CSN. For these pins, the first name

(TEST, AC2, AC1, AC0, IF1, IF0) indicates their function when they are sampled by the rising edge of the RSTN pin.

The second name refers to their function after reset. The values of these pins are latched into the CFGSR register

when RSTN goes high. To ensure the device properly samples the reset values of these pins, the following guidelines

should be followed:

Any pullup or pulldown resistors used to set the value of these pins at reset should be 1k

.

RSTN must be asserted at least as long as specified in section 5.9.

The hardware configuration pins are grouped into three sets:

TEST - Manufacturing test mode

IF[1:0]

– Microprocessor interface mode and I2C address

AC[2:0]

– Auto-config configuration number (0 to 7)

The TEST pin selects manufacturing test modes when TEST=1 (the AC[2:0] pins specify the test mode). For ZL30261

and ZL30263 (devices with internal EEPROM), TEST=1, AC[2:0]=000, IF[1:0]=11 configures the part so that

production SPI EEPROM programmers can program the internal EEPROM (see section 5.11.2). TEST=1 and

AC[2:0]=011 causes the part to start normally except it does not auto-configure from EEPROM or ROM. For more

information about auto-configuration from EEPROM or ROM see section 5.11.

For all of these pins Microchip recommends that board designs include component sites for both pullup and pulldown

resistors (only one or the other populated per pin).
