PCA9665; PCA9665A
Fm+ parallel bus to I2C-bus controller
Rev. 4 — 29 September 2011
Product data sheet
1. General description
The PCA9665/PCA9665A serves as an interface between most standard parallel-bus
microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus
system to communicate bidirectionally with the I2C-bus. The PCA9665/PCA9665A can
operate as a master or a slave and can be a transmitter or receiver. Communication with
the I2C-bus is carried out on a Byte or Buffered mode using interrupt or polled handshake.
The PCA9665/PCA9665A controls all the I2C-bus specific sequences, protocol, arbitration
and timing with no external timing element required.
The PCA9665 and PCA9665A have the same footprint as the PCA9564 with additional
features:
1 MHz transmission speeds
Up to 25 mA drive capability on SCL/SDA
68-byte buffer
I2C-bus General Call
Software reset on the parallel bus
2. Features and benefits
Parallel-bus to I2C-bus protocol converter and interface
Both master and slave functions
Multi-master capability
Internal oscillator trimmed to 15 % accuracy reduces external components
1 Mbit/s and up to 25 mA SCL/SDA IOL (Fast-mode Plus (Fm+)) capability
I2C-bus General Call capability
Software reset on parallel bus
68-byte data buffer
Operating supply voltage: 2.3 V to 3.6 V
5 V tolerant I/Os
Standard-mode and Fast-mode I2C-bus capable and compatible with SMBus
PCA9665A ‘glitch-free’ restart is suitable for use with buffer drivers
ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per
JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
Packages offered:
PCA9665: SO20, TSSOP20, HVQFN20
PCA9665A: TSSOP20

3. Applications
Add I2C-bus port to controllers/processors that do not have one
Add additional I2C-bus ports to controllers/processors that need multiple I2C-bus ports
Converts 8 bits of parallel data to serial data stream to prevent having to run a large
number of traces across the entire printed-circuit board
