Line 1: {{Short description\|PPI: Parallel Peripheral Interface (2001, USA)}} ~~{{Unreferenced\|date=September 2009}}~~ {{Multiple issues\| {{More citations needed\|date=February 2022}} {{Notability\|date=March 2015}} }} The '''Parallel Peripheral Interface''' ('''PPI''') is a peripheral found on the [[Blackfin]] embedded processor. The PPI is a [[half-duplex]], [[Two-way communication\|bi-directional]] port that is designed to connect directly to [[LCD]]s, [[CMOS sensor]]s, [[Charge-coupled device\|CCD]]s, video encoders (video [[Digital-to-analog converter\|DAC]]s), video decoders (video [[Analog-to-digital converter\|ADC]]s) or any generic high speed, parallel device.<ref>{{Cite web\|title=PPI: Parallel Peripheral Interface [Analog Devices Wiki]\|url=https://wiki.analog.com/resources/eval/sdp/sdp-b/peripherals/ppi\|access-date=2021-10-01\|website=wiki.analog.com}}</ref> The width of the PPI is programmable and can be set between 8 and 16- bits in 1 -bit increments. The latest Blackfin family (BF54x) also features an 18/24-bit PPI for direct connection to [[RGB]] LCD panels. The PPI can run from 0 [[MHz]] up to 66 MHz. The PPI has a dedicated clock pin, three multiplexed frame sync pins, and between 16 and 24 data pins.<ref>{{Cite web\|last=Y\|first=Roshni\|date=2019-07-04\|title=What is 8255 Programmable Peripheral Interface (PPI)?
