CPU Supervisor with Nonvolatile Memory and Programmable I/O
General DescriptionThe DS4510 is a CPU supervisor with integrated 64-
byte EEPROM memory and four programmable, non-
volatile (NV) I/O pins. It is configured with an
industry-standard I2C™ interface using either fast-
mode (400kbps) or standard-mode (100kbps) commu-
nication. The I/O pins can be used as general-purpose
I2C-to-parallel I/O expander with unlimited read/write
capability. EEPROM registers allow the power-on value
of the I/O pins to be adjusted to keep track of the sys-
tem’s state through power cycles, and the CPU supervi-
sor’s timer can be adjusted between 125ms and
1000ms to meet most any application need.

inputs do not violate their min and max input voltage levels.
Note 3:ISTBY specified with VCCequal to 5.0V, and control port-logic pins are driven to ground or VCCfor the corresponding
inactive state (SDA = SCL = VCC), does not include pullup resistor current.

Note 5:This parameter is guaranteed by design.
Note 6:I2C interface timing shown for is for fast-mode (400kHz) operation. This device is also backward compatible with I2C
standard-mode timing.
Note 7:CB—total capacitance of one bus line in picofarads.
Note 8:EEPROM write time applies to all the EEPROM memory and SEEPROM memory when SEE=0. The EEPROM write time
begins at the occurrence of a stop condition.

DS4510
CPU Supervisor with Nonvolatile Memory and
Programmable I/O
Detailed DescriptionThe DS4510 contains a CPU supervisor, four program-
mable I/O pins, and a 64-byte EEPROM memory. All
functions are configurable or controllable through an
industry-standard I2C-compatible bus. DS4510 NV reg-
isters that are likely to require frequent modification are
implemented using SRAM-shadowed EEPROM (SEEP-
ROM) memory. This memory is configurable to act as
volatile SRAM or NV EEPROM by adjusting the SEEbit
in the Config register. Configuring the SEEPROM as
SRAM eliminates the EEPROM write time and allows
infinite write cycles to these registers. Configuring the
registers as EEPROM allows the application to change
the power-on values that are recalled during power-up.
Programmable CPU SupervisorThe timeout period is adjusted by writing the reset
delay register (SEEPROM). The delay for each setting
is shown in the CPU Supervisor AC Electrical
Characteristics. If the SEEbit is set, changes are writ-
ten to SRAM. On power-up the last value written to the
EEPROM is recalled. The I2C bus is also used to acti-
vate the RSTby setting the SWRST bit in the Config
register. This bit automatically returns to zero after the
timeout period. The Config register also contains theready, trip point, and reset status bits. The readybit
determines if the power-on reset level of the DS4510 is
surpassed by VCC. The trip point bit determines if VCC
is above VCCTP, and the reset status bit is set if RSTis
in its active state.
Note: The RSTpin is an open-drain output, therefore an
external pullup resistor must be used to realize high
logic levels.
Programmable NV Digital I/O PinsEach programmable I/OXpin contains an input, open-
collector output, and a selectable internal pullup resis-
tor. The DS4510 stores changes to the I/OXpin in
SEEPROM memory. Using the SEEPROM as SRAM is
conducive to applications such as I/O expansion that
generally require fast access times and frequent modi-
fication of the I/OXpin. Configuring the SEEPROM to
behave as EEPROM allows the modification of the
power-on state of the I/OXpin. During power-up the
I/OXpins are high impedance until VCCexceeds 2.0V
(typically), which is when the last value programmed is
recalled from EEPROM. On power-down, the I/OXstate
is maintained until VCCdrops below 1.9V (typically).
The internal pullups for each I/OXpin are controlled by
the pullup-enable register (F0h). Similarly, the individual
I/OXcontrol registers (F4h to F7h) adjust the pulldown
