1 / 28 page SM5M2 - 1 - In the absence of confirmation by device specification sheets, SHARP takes no responsibility for any defects that may occur in equipment using any SHARP devices shown in catalogs, data books, etc. Contact SHARP in order to obtain the latest device specification sheets before using any SHARP device. DESCRIPTION The SM5M2 is a CMOS 4-bit single-chip micro- computer operated on 3.0 V single power supply. This microcomputer integrates 4-bit parallel processing function, ROM, RAM, display RAM, 15- stage divider, 2-kind of interrupt and 4-level of subroutine stack. With a built-in LCD drive circuit for a maximum of 136 elements, a 2-mode standby function, voice synthesizer and a melody generator circuit in a single chip, the SM5M2 permits the design of system configuration with a minimum of peripheral components. It can be used in a variety of products from handheld equipment to electrical appliances, such as hand held games with voice, and also achieves low power consumption. FEATURES • ROM capacity : 3 072 x 8 bits (For main program) 64k x 5 bits (For voice) 256 x 6 bits (For melody) • RAM capacity : 130 x 4 bits (including 34 x 4 bits display RAM) • Instruction sets : 51 • Subroutine nesting : 4 levels • I/O port : Input 1 Output 6 Input/output 7 • Interrupts : Internal interrupt x 1 (divider overflow) External interrupt x 1 (INTA) • Built-in voice synthesizer circuit (APCM) : Number of phrases : 256 Voice ROM : 64 k x 5 bits Bit rate : 25/35 kbps Number of coded bit : 5 bits Sampling frequency : 5/7 kHz Generation period : 9.1 to 12.8 s • Built-in main clock oscillator for system clock • Built-in sub clock oscillator for real time clock PIN CONNECTIONS • Built-in 15 stages divider for real time clock • Built-in LCD driver : 136 segments, 1/2 bias, 1/4 duty cycle • Built-in melody generator circuit : Melody ROM : 256 steps Generating time (at 32.768 kHz) : 32 s (MAX.) • Instruction cycle time : 25.9 µs (MIN.) (at 70 kHz ± 10%) 61 µs∗ (TYP.) (at 32.768 kHz) ∗When using the clock with the system clock. • Standby function • Supply voltage : 2.4 to 3.3 V • Package : 72-pin QFP (QFP072-P-1010) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 (NC) S25 S24 S23 S22 S21 S20 S19 S18 S17 S16 S15 S14 S13 S12 16 17 18 39 38 37 S11 S10 (NC) 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 34 35 36 57 56 55 INTA (NC) P00 P01 P02 P03 P10 P11 P12 P13 P20 P21 P22 T F VOICE VR VDD SM5M2 4-Bit Single-Chip Microcomputer (LCD Driver) 72-PIN QFP TOP VIEW |
