i.MX23 EVK Hardware User’s Guide, Rev 1.1
Provides support for Super JTAG trace mode. Connects to CPLD to
convert JTAG data to proprietary serial data for use by the i.MX23
IC. Additional data is sent over LCD Data lines. When in use, RGB-
LCD operations is prohibited
Three pin connector allows for the attachment of Li-ION batteries
with a
3 x 1 pin header version of Battery Connector socket. Allows for the
use of generic Li-ION Batteries or an external power supply.
D-SUB9 Connector is driven by a MAX3222 UART Driver IC to
provide a Serial Debug Communications port. i.MX23 IC provides
debug data over PWM0 and PWM1 pins to the Driver IC. There are
no hardware flow control operations on the Debug UART.
D-SUB9 Connector is driven by a MAX3222 UART Driver IC to
provide an Application Serial Communications Port. i.MX23 IC
provides debug data over UART1: TX, RX, CTS, RTS pins to the
Driver IC.
Optional D-SUB9 Connector is driven by a MAX3222 UART Driver
IC to provide a second Application Serial Communications Port if
desired. i.MX23 IC provides debug data over GPMI: D14, D15 for
receive and transmit. ROTARY: A, B can supply flow control if
necessary.
Optional 8-pin DIP Socket can be added to allow EVK user to plug
in various SPI Flash ICs, in lieu of soldering SPI Flash directly down
on the EVK board.. SPI Flash uses same SPI Header as SD/MMC
card and Ethernet. When SPI Flash is inserted, SD/MMC card can
not be inserted and Ethernet communications must be disabled.
Additional resistors and capacitors must be added to support SPI
Flash operations.
Optional 8-pin DIP Socket can be added to allow EVK user to plug
in various I2C EEPROM ICs, in lieu of soldering an EEPROM
directly down on the EVK board. Socket connects directly to I2C
header of i.MX23 IC, which is shared by various other ICs.
120-Pin high speed, high density connector designed to fit optional
4.3” WQVGA touch screen display panel. Other panels may
become available for use by the EVK over the lifecycle of the
i.MX23 IC.
120-Pin high speed, high density connector designed to fit optional
expansion boards which may become available over the lifecycle of
the i.MX23 IC.
Used for internal Freescale, large quantity, automated testing.
Connected to the LRADC pins of the i.MX23 IC, this optional header
allows the user access to connect LRADC inputs to the CPU for
uses other than those normally used by the EVK.
Used for internal Freescale, large quantity, automated testing.
Connected to Xilinx CPLD programming pins to allow in-situ
programming of the CPLD.
User can cut the traces between the two pins, install a 2 x 1 Header
and attach a current probe between the pins to readily measure
current drawn from the battery.
