SM6006

PRODUCT INFORMATION ® APPLICATIONS: PDA Digital Camera Integrated Circuits Group SM6004/SM6006 16-Bit Single-Chip Microcomputers FEATURES ROM capacity: – 61,440 × 8-bits (SM6004) – 126,976 × 8-bits (SM6006) RAM capacity: – 2,048 × 8-bits (SM6004) – 3,584 × 8-bits (SM6006) External memory expansion function – On chip bus controller for external memory – Bus multiplexing/nonmultiplexing selection – Bus width selection – Auto wait control CPU – General purpose registers 16-bit × 16 – 62 basic instructions (bit manipulation instructions Suitable for controlling, bit transfer instructions, bit branch instructions, high speed multiplication and division instructions (16-bits × 16-bits, 16-bits ÷ 16-bits, 32-bits ÷ 16-bits)) 10 addressing modes – 16M of address space – An interrupt request starts a high performance automatic data transfer (DTS). Appropriate settings of interrupts and registers enable hardware automatic data transfer. Various functions can be operated successively and the resultant data can also successively be stored. – System clock cycle 0.133 µs (MIN.) (VDD = 4.5 V to 5.5 V at 30 MHz main clock cycle) – 0.2 µs (MIN.) (VDD = 2.5 V to 5.5 V at 20 MHz main clock cycle) – Selectable system clocks divided by 2 up to 16 main clocks for low power operation. 27 total software interrupts – 24 maskable interrupts (external 4, internal 20) – 3 nonmaskable interrupts – A nonmaskable interrupt, when used in conjunction with BST instruction, can trigger the so...
