Product Overview
The APIO16 is a radiation-hardened by design level translating I2C, SMBUS, SPI I/O expander that is ideally suited for space, medical imaging and other applications demanding radiation tolerance and high reliability. It is fabricated in a BiCMOS process utilizing proprietary radiation-hardening techniques, delivering high resiliency to single-event effects (SEE) and to a total ionizing dose (TID) as might be found in a Low Earth Orbit (LEO) environment.
- 1.4 VDC to 5.5 VDC with level shifting capability between serial and parallel bus
- Designed for military temperature environments (-55 °C to +125 °C)
- Schmitt trigger and noise filter on I²C interface inputs and all port inputs
- Select between SPI and I²C/SMBus protocols with a MODE pin
- 16 configurable I²C addresses
- Fast-mode-plus I²C up to 1 MHz and SPI operation up to 25 MHz
- Open drain INTB pin to alert controller when inputs change
- Input/Output configuration register
- Latched outputs with 25mA drive capability
- Cold sparable I/Os
- Internal power-on reset, no glitch on power-up
- Built-in triple redundancy for reliability
- Class 2 ESD protection (4000 V HBM, 500 V CDM)
- 28-pin TSSOP packaging
- Expand number of I/O’s for MCUs and FPGAs
- Voltage level translation between legacy peripherals and modern FPGAs
- Health monitoring for remote systems
- Serialize peripheral monitoring signals
- Reduce harness size and weight
- Cold sparable IOs for primary redundant systems
