NJU3152

NJU3152 PRELIMINARY 4-BIT SINGLE CHIP OTP TINY CONTROLLER s GENERAL DESCRIPTION The NJU3152 is the C-MOS 4-bit Single Chip OTP type Micro Controller with programmable Flash Memory. It is completely compatible with the NJU3102 in function and the pin configuration. Therefore, the NJU3152 is suitable for the final evaluation before NJU3102 mask generation, the small quantity production and short leadtime. * In this data sheet, only OTP programming and the difference between NJU3152 and NJU3102 are mentioned mainly. Therefore the detail function and specification should be referred on the NJU3102 data sheet. s PACKAGE OUTLINE NJU3152L NJU3152G s FEATURES q q q q q Internal One Time Programmable ROM 1,024 X 8bits Internal Data RAM 32 X 4bits Wide operating voltage range 2.7V ~ 5.5V Package outline SDIP22 / SOP22 ROM programmer “SUPERPRO/L” by XELTEK co,. s PIN CONFIGURATION IN OTP PROGRAMMING MODE Open D0 D1 D2 Open D3 Open PROM CLK REQ VSS 1 2 3 4 5 6 7 8 9 10 11 22 21 20 19 18 17 16 15 14 13 12 VDD Open CNT2 CNT1 D7 Open D6 D5 D4 RESET Note) The pin configuration in Normal operating mode is the same as NJU3102. -1- NJU3152 s BLOCK DIAGRAM CPU CORE STACK TLUaddr MUX OTP ROM 1024 x 8 bit IR RAM 32 x 4 bit ID STANDBY CONTROLLER ALU CPU TIMING GENERATOR OSC TEST RESET OSC1 OSC2 PC X’-Reg Y’-Reg X-Reg Y-Reg AC VDD VSS PORT_A PORT_B PORT_E PORT_D PORT_C PD0 PD1 PD2 PD3 PC0 -2- PC1 PB0 PB1 PB2 PB3 PE0 PE1 PA0 PA1 PA2 PA3 NJU3152 s TERMINAL DESCRIPTION IN OT...
