- 8K word program ROM access and 8-level stacks
- Multi melody channels can be played simultaneously (8 channels for EM61100~ EM61400, 4 channels for EM61001 and EM61002)
- On chip voice ROM will extend up to 512K Bytes
- Uses real instrument waveforms for good quality audio melody
- Built-in 8-bit by 8-bit hardware multiplier with 16-bit result
- One 8-bit input port and one 8-bit I/O port with pull-low/wake-up functions
- Provides additional general-purpose I/O ports (up to 3 ports)
- Provides crystal oscillation or internal oscillator (by connecting a resistor)
