Description
The SS8203A is a high performance CMOS 8-bit microcontroller with 32Kbytes
of Flash programmable and erasable read only memory. The device uses the
industry standard 8051 instruction set with an extensive set of peripherals to
provide user with a powerful solution for consumer appliance applications.
The Silconians SS8203A also provides the user with 256 bytes of additional
onchip data memory accessible by the MOVX command(XRAM). This makes a total
of 512 bytes of onchip data ram. The versatile design also allows the user to
access additional external program rom or data ram up to 64Kbytes.
The extensive SS8203A peripheral set includes 32Kbyte Flash electrically erasable
eprom, 512 bytes data RAM, 40 I/O lines, two serial I/O, two 16 bit timers
and six 8 bit timers. In addition there is a 10 channel 8 bit A/D, and 17 two level
vectored interrupts. The SS8203A is designed for low power with 5 power
saving programmable modes using two on-chip oscillators at 12Mhz and
32Khz and the CPU halt mode.
