16/32-bit ARM microcontrollers with external memory interface
Rev. 02— 30 May 2005
Description
A19 — External memory address line 19.
A20 — External memory address line 20.
A21 — External memory address line 21.
A22 — External memory address line 22.
A23 — External memory address line 23.
XCLK — Clock output.
CS3 — LOW-active Chip Select 3 signal.
(Bank 3 addresses range 8300 0000 to 83FF FFFF)
CS2 — LOW-active Chip Select 2 signal.
(Bank 2 addresses range 8200 0000 to 82FF FFFF)
CS1 — LOW-active Chip Select 1 signal.
(Bank 1 addresses range 8100 0000 to 81FF FFFF)
WE — LOW-active Write enable signal.
BLS3 — LOW-active Byte Lane Select signal (Bank 3).
AIN7 — A/D converter, input 7. This analog input is always
connected to its pin.
BLS2 — LOW-active Byte Lane Select signal (Bank 2).
AIN6 — A/D converter, input 6. This analog input is always
connected to its pin.
BLS1 — LOW-active Byte Lane Select signal (Bank 1).
BLS0 — LOW-active Byte Lane Select signal (Bank 0).
Not connected. This pin MUST NOT be pulled LOW or the
device might not operate properly.
External reset input: A LOW on this pin resets the device,
causing I/O ports and peripherals to take on their default
states, and processor execution to begin at address 0. TTL
with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator
circuits.
Output from the oscillator amplifier.
Ground: 0 V reference.
Analog ground: 0 V reference. This should nominally be the
same voltage as V
and error.
PLL analog ground: 0 V reference. This should nominally be
the same voltage as V
noise and error.
1.8 V core power supply: This is the power supply voltage
for internal circuitry.
