3 / 49 page SM8954B 8-Bit Micro-controller 16KB Flash & 1KB RAM embedded Specifications subject to change without notice contact your sales representatives for the most recent information. ISSFD-M083 Ver D SM8954B 08/07/2015 - 3 - Product List SM8954BW40PP, SM8954BW44JP, SM8954BW44QP, Description The SM8954B series product is an 8 - bit single chip micro controller with 16KB flash & 1KB SRAM embedded. SM8954B is a versatile and cost effective controller for those applications which demand up to 36 I/O pins, or applications which need up to 16K byte flash memory either for program or for data or mixed. To program the on-chip flash memory, a commercial writer is available to do it in parallel programming method.
