TC1321
10-Bit Digital-to-Analog Converter with Two-Wire Interface
Features
General Description
•
•
•
•
The TC1321 is a serially accessible, 10-bit voltage
output, digital-to-analog converter (DAC). The DAC
produces an output voltage that ranges from ground to
an externally supplied reference voltage. It operates
from a single power supply that can range from 2.7V to
5.5V, making it ideal for a wide range of applications.
Built into the part is a Power-on Reset (POR) function
that ensures that the device starts at a known condition.
10-Bit Digital-to-Analog Converter
2.7-5.5V Single Supply Operation
Simple SMBus/I2CTM Serial Interface
Low Power Operation
- Normal Mode: 350 µA
- Shutdown Mode: 0.5 µA
• Temperature Range: 40°C to +85°C
• 8-Pin SOIC and 8-Pin MSOP Packages
Communication with the TC1321 is accomplished via a
simple 2-wire SMBus/I2C compatible serial port, with
the TC1321 acting as a slave only device. The host can
enable the SHDN bit in the CONFIG register to activate
the Low Power Standby mode.

DETAILED DESCRIPTION
3.2
Output Amplifier
The TC1321 is a monolithic 10-bit digital-to-analog
converter that is designed to operate from a single
supply that can range from 2.7V to 5.5V. The DAC
consists of a data register (DATA), a configuration
register (CONF), and a current output amplifier. The
TC1321 uses an external reference which also
determines the maximum output voltage.
The TC1321 DAC output is buffered with an internal
unity gain rail-to-rail input/output amplifier with a typical
slew rate of 0.8V/µs. Maximum full scale transition
settling time is 10 µsec to within ±1/2LSB when loaded
with 1 k in parallel with 100 pF.
The TC1321 uses a current steering DAC based on an
array of matched current sources. This current, along
with a precision resistor, converts the contents of the
DATA Register and VREF into an output voltage, VOUT,
that is given by:
The TC1321 allows the host to put it into a Low Power
(IDD = 0.5 µA, typically) Standby mode.
DATA
V OUT = VREF ---------------1024
3.1
3.3
In this mode, the D/A conversion is halted. The SMBus
port operates normally. Standby mode is enabled by
setting the SHDN bit in the CONFIG register. Table 3-1
summarizes this operation.
TABLE 3-1:
Reference Input
The reference pin, VREF, is a buffered high-impedance
input. Because of this, the load regulation of the
reference source needs only to be able to tolerate
leakage levels of current (less than 1 µA). VREF
accepts a voltage range from 0 to (VDD – 1.2V). Input
capacitance is typically 10 pF.

SERIAL PORT OPERATION
4.1
START Condition (START)
The Serial Clock input (SCL) and bi-directional data
port (SDA) form a 2-wire bi-directional serial port for
programming and interrogating the TC1321. The
following conventions are used in this bus architecture.
The TC1321 continuously monitors the SDA and SCL
lines for a START condition (a HIGH to LOW transition
of SDA while SCL is HIGH), and will not respond until
this condition is met.
TABLE 4-1:
4.2
Term
TC1321 SERIAL BUS
CONVENTIONS
Explanation
Transmitter The device sending data to the bus.
Receiver
The device receiving data from the bus.
Master
The device that controls the bus: initiating
transfers (START), generating the clock, and
terminating transfers (STOP)
Slave
The device addressed by the master.
START
A unique condition signaling the beginning of
a transfer, indicated by SDA falling (High Low) while SCL is high.
STOP
A unique condition signaling the end of a
transfer, indicated by SDA rising (Low - High)
while SCL is high.
Address Byte
Immediately following the START condition, the host
must transmit the address byte to the TC1321. The
7-bit SMBus address for the TC1321 is 1001000. The
7-bit address transmitted in the serial bit stream must
match for the TC1321 to respond with an Acknowledge
(indicating the TC1321 is on the bus and ready to
accept data). The eighth bit in the Address Byte is a
Read-Write bit. This bit is a 1 for a read operation or 0
for a write operation. During the first phase of any
transfer, this bit will be set = 0 to indicate that the
command byte is being written.
4.3
Acknowledge (ACK)
ACK
A receiver acknowledges the receipt of each
byte with this unique condition. The receiver
drives SDA low during SCL, high of the ACK
clock pulse.The master provides the clock
pulse for the ACK cycle.
Acknowledge (ACK) provides a positive handshake
between the host and the TC1321. The host releases
SDA after transmitting eight bits, then generates a ninth
clock cycle to allow the TC1321 to pull the SDA line
LOW to Acknowledge that it successfully received the
previous eight bits of data or address.
Busy
Communication is not possible because the
bus is in use.
4.4
Not Busy
When the bus is IDLE, both SDA and SCL will
remain high.
Data Valid
The state of SDA must remain stable during
the High period of SCL in order for a data bit
to be considered valid. SDA only changes
state while SCL is low during normal data
transfers. See START and STOP conditions.
All transfers take place under control of a host, usually
a CPU or microcontroller, acting as the master, which
provides the clock signal for all transfers. The TC1321
always operates as a slave. The serial protocol is
illustrated in Figure 4-1. All data transfers have two
phases; all bytes are transferred MSB first. Accesses
are initiated by a START condition (START), followed
by a device-address byte and one or more data bytes.
The device-address byte includes a Read/Write
selection bit. Each access must be terminated by a
STOP Condition (STOP). A convention called
Acknowledge (ACK) confirms receipt of each byte.
Note that SDA can change only during periods when
SCL is LOW (SDA changes while SCL is HIGH are
reserved for START and STOP conditions).
2010 Microchip Technology Inc.
Data Byte
After a successful ACK of the address byte, the host
must transmit the data byte to be written or clock out
the data to be read. (See the appropriate timing
diagrams.) ACK will be generated after a successful
write of a data byte into the TC1321.
4.5
Stop Condition (STOP)
Communications must be terminated by a STOP
condition (a LOW to HIGH transition of SDA while SCL
is HIGH). The STOP condition must be communicated
by the transmitter to the TC1321. Refer to Figure 4-1,
for serial bus timing.

2010 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

IMPLIED, WRITTEN OR ORAL, STATUTORY OR
OTHERWISE, RELATED TO THE INFORMATION,
INCLUDING BUT NOT LIMITED TO ITS CONDITION,

arising from this information and its use. Use of Microchip
