Overview
DATA SHEET MOS INTEGRATED CIRCUIT µ PD16314 DOT CHARACTER VFD CONTROLLER/DRIVER DESCRIPTION The µ PD16314 is a VFD controller/driver capable of displaying a dot matrix VFD.
It has 80 anode outputs and 24 grid outputs.
A single µ PD16314 can display up to 16C x 2L, 20C x 2L, or 24C x 2L.
The µ PD16314 has character generator ROM in which 248 x 5 x 8 dot characters are stored.
FEATURES • Dot matrix VFD controller/driver • Capable of driving anodes for cursor display (48 units) • 80 x 8 bits display RAM incorporated • Capable of alphanumeric and symbolic display through internal ROM (5 by 8 dots) 240 characters plus 8 user-defined characters • Display contents 16 columns by 2(1) rows + 32(16) cursors, 20 columns by 2(1) rows + 40(20) cursors, or 24 columns by 2(1) rows + 48(24) cursors.
• Parallel data input/output (switchable between 4 bits and 8 bits) or serial data input/output can be selected.
• On-chip oscillator • Custom ROM supported ORDERING INFORMATION Part Number Package 144-PIN PLASTIC LQFP(FINE PITCH)(20x20), Standard ROM (ROM code: 001) 144-PIN PLASTIC LQFP(FINE PITCH)(20x20), Standard ROM (ROM code: 002) µ PD16314GJ-001-8EU µ PD16314GJ-002-8EU The information in this document is subject to change without notice.
