Pin Description Table
in Description Table
The following table lists the functions of the pins provided on the RC32434. Some of the functions listed may be multiplexed onto the same pin.
The active polarity of a signal is defined using a suffix. Signals ending with an “N” are defined as being active, or asserted, when at a logic zero
(low) level. All other signals (including clocks, buses, and select lines) will be interpreted as being active, or asserted, when at a logic one (high) level.
Signal
Type
Name/Description
Memory and Peripheral Bus
BDIRN
O
External Buffer Direction. Controls the direction of the external data bus buffer
for the memory and peripheral bus. If the RC32434 memory and peripheral bus
is connected to the A side of a transceiver, such as an IDT74FCT245, then this
pin may be directly connected to the direction control (e.g., BDIR) pin of the
transceiver.
BOEN
O
External Buffer Enable. This signal provides an output enable control for an
external buffer on the memory and peripheral data bus.
WEN
O
Write Enables. This signal is the memory and peripheral bus write enable sig-
nal.
CSN[3:0]
O
Chip Selects. These signals are used to select an external device on the mem-
ory and peripheral bus.
MADDR[21:0]
O
Address Bus. 22-bit memory and peripheral bus address bus.
MADDR[25:22] are available as GPIO alternate functions.
MDATA[7:0]
I/O
Data Bus. 8-bit memory and peripheral data bus. During a cold reset, these pins
function as inputs that are used to load the boot configuration vector.
OEN
O
Output Enable. This signal is asserted when data should be driven by an exter-
nal device on the memory and peripheral bus.
RWN
O
Read Write. This signal indicates whether the transaction on the memory and
peripheral bus is a read transaction or a write transaction. A high level indicates
a read from an external device. A low level indicates a write to an external
device.
WAITACKN
I
Wait or Transfer Acknowledge. When configured as wait, this signal is
asserted during a memory and peripheral bus transaction to extend the bus
cycle. When configured as a transfer acknowledge, this signal is asserted during
a transaction to signal the completion of the transaction.
DDR Bus
DDRADDR[13:0]
O
DDR Address Bus. 14-bit multiplexed DDR address bus. This bus is used to
transfer the addresses to the DDR devices.
DDRBA[1:0]
O
DDR Bank Address. These signals are used to transfer the bank address to the
DDRs.
DDRCASN
O
DDR Column Address Strobe. This signal is asserted during DDR transac-
tions.
DDRCKE
O
DDR Clock Enable. The DDR clock enable signal is asserted during normal
DDR operation. This signal is negated following a cold reset or during a power
down operation.
DDRCKN
O
DDR Negative DDR clock. This signal is the negative clock of the differential
DDR clock pair.
