• Memory
− Program ROM (P-ROM): 32K × 20 (ROM Bank0, 1, 2)
− Data RAM (W-RAM): 1.4K × 4 bit
(RAM Bank 0 is 896 nibbles from 0:000 ~0:37F and 0:380~0:3FF are mapped to special register.
RAM Bank F is 512 nibbles from F:200 ~F:3FF either data RAM or dedicated to script kernel )
− LCD RAM (L-RAM): 256× 4 bit × 2 pages (RAM Bank1, 2 from 200~2FF)
• Maximum 24 input/output pads
− Ports for input only: 8 pads (RC, RD port; RD1~3 can share as serial bus for external memory
W55XXX interface @W536030A/060A)
− Ports for output only: 8 pads (RE & RF port; W536090A/120A available only)
− Ports for Input/output: 8 pads (RA and RB port; RB port is available for W536060A/090A/120A
only)
• Power-down mode
− Hold mode (except for 32kHz oscillator)
− Stop mode (including 32kHz oscillator and release by RD or RC port)
• Eight types of interrupts
− Five internal interrupts (Divider, Timer 0, Timer 1, Speech, Melody)
− Three external interrupts (Port RC, RD, RA)
