MITMSITUSBUISBHISI H〈DI I〈GDIITGAITLAALSASSPS〉 P〉 M6600M466S0P04/SFPP/FP DESCRIPTION The M66004 is a 16-digit 5×7-segment vacuum fluorescent display (VFD) controller using the silicon gate CMOS tech- nology. It contains 160 ROM characters and 16 user-defined RAM characters and receives display character codes and various commands from MCU to control VFD. FEATURES • Built in 5×7-dot segment character ROM (160 characters based on JIS-C-6220. Customization is possible.) • Built in character RAM for user definition (16 characters) • Display digit length can be changed. (from 9 to 16 digits) • One-digit display cycle setting can be changed. (2 cycles) • Dimmer is adjustable. (8 grades) • Cursor display ON or OFF is selectable. (SEG35 output) • Built in automatic display digit increment function • Auto increment of display digit • Built in simultaneous all-digit display ON/OFF command • Connection to MCU by three signal lines, CS, SCK and SDATA • Instruction execution with one byte* • 2 general purpose output ports • Positive supply voltage VCC=5V ± 10% • Pull-down voltage VP=VCC-40V typ. VCC-45V max. (peak) : Except for character RAM setting APPLICATION AV equipments, vacuum fluorescent display controller for POS system, etc. FUNCTION The M66004 is a 16-digit 5×7-segment VFD (Vacuum Fluo- rescent Display) controller and contains 160 ROM characters based on JIS-C-6220 which can be customized and 16 RAM characters that user can define freely. Character display codes and various commands are re- ceived as 8-bit serial data from MCU. Main functions of this IC are display digit length setting, one- digit display cycle setting and dimmer adjustment. It has 36 segment output pins from SEG00 to SEG35 and uses 35 pins from SEG00 to SEG34 for character display. SEG35 output, which is independent of other segment, is used for cursor display by inputting either cursor ON or OFF command. Once display data is fixed, display continues automatically until new data is input. Therefore, MCU can execute other jobs and is lightened of its load. Additionally, the IC can control other I/O elements because it contains two static operation output ports. 16-1D6I-GDIITG5IT×75-XS7E-GSEMGEMNETNVTFDVFCDOCNOTRNOTRLLOELRLER  DIG11 ← 1   DIG10 ← 2   DIG09 ← 3   DIG08 ← 4   DIG07 ← 5  DIG06 ← 6 Digit outputs   DIG05 ← 7   DIG04 ← 8   DIG03 ← 9   DIG02 ← 10  DIG01 ← 11   DIG00 ← 12 Reset input RESET → 13 Chip select input CS → 14 Shift clock input CSK → 15 Serial data input SDATA → 16  Output ports   P1 ← 17 P0 ← 18 VCC1 19 Clock output XOUT ← 20 Clock input XIN → 21 VSS 22 SEG35 ← 23   SEG34 ← 24   SEG33 ← 25   SEG32 ← 26 Segment outputs SEG31 ← 27   SEG30 ← 28   SEG29 ← 29 SEG28 ← 30   SEG27 ← 31 VP 32 64 → DIG12  63 → DIG13   62 → DIG14  Digit output  61 → DIG15   60 VCC2 59 → SEG00  58 → SEG01   57 → SEG02   56 → SEG03   55 54 → → SEG04 SEG05    53 → SEG06   52 → SEG07   51 → SEG08   50 → SEG09  49 → SEG10   48 → SEG11   47 → SEG12   Segment outputs 46 → SEG13   45 → SEG14   44 → SEG15  43 → SEG16   42 → SEG17   41 → SEG18   40 39 → → SEG19 SEG20    38 → SEG21   37 → SEG22   36 → SEG23   35 → SEG24  34 → SEG25   33 → SEG26   Outline 64P4B 64P2G-A 1 1 page MITSUBISHI 〈DIGITAL ASSP〉 M66004SP/FP 16-DIGIT 5X7-SEGMENT VFD CONTROLLER COMMAND LIST Function Display digit length setting Command code D7 D6 D5 D4 D3 D2 D1 D0 Contents The number of digits to display is fixed.
