OM5234 Datasheet | NXP Semiconductors

DESCRIPTION The OM5234 and OM5284 single-chip 8-bit microcontrollers are manufactured in an advanced CMOS process and are derivatives of the 80C51 microcontroller family. The OM5234 and OM5284 are pre-programmed devices for specific applications. Unless specifically stated otherwise, all references to OM5234 apply equally to OM5284. The OM5234 contains a non-volatile 16k × 8 read-only program memory, a volatile 256 × 8 read/write data memory, four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51), a multi-source, two-priority-level, nested interrupt structure, UART and on-chip oscillator and timing circuits. FEATURES - 80C51 central processing unit - 6k × 8 ROM - 256 × 8 RAM - Two standard 16-bit timer/counters - Four 8-bit I/O ports - Full-duplex UART facilities - Power control modes - Idle mode - Power-down mode - ROM code protection ORDERING INFORMATION OM5234 / F T P / YYY Device OM5234 Frequency Range F = 3.5 to 16MHz I = 3.5 to 24MHz Temperature Range B = 0 to 70°C PART NUMBER OM5234/FBB/YYY OM5234/FBP/YYY OM5234/FBA/YYY OM5284EBYY OM5284EAYY OM5284EPYY ROM code for application 5XX, etc. Package designator A = Plastic Leaded Chip Carrier B = Plastic Quad Flat Package P = Plastic Dual In-Line Package Device OM5284 Frequency Range E = 3.5 to 16MHz I = 3.5 to 24MHz OM5284 X Y ZZ ROM code for application 01, 02, 03 Package designator A = Plastic Leaded Chip Carier B = Plastic Quad Flat Package P = Plastic Dual In-Line Package FREQUENCY (MHz) 16 16 16 16 16 16 DRAWING NUMBER SOT307-2 SOT129-1 SOT187-2 SOT307-2 SOT187-2 SOT129-1 TEMPERATURE RANGE °C AND PACKAGE 0 to 70°C, Plastic Quad Flat Package 0 to 70°C, Plastic Dual In-Line Package 0 to 70°C, Plastic Leaded Chip Carrier 0 to 70°C, Plastic Quad Flat Package 0 to 70°C, Plastic Leaded Chip Carrier 0 to 70°C, Plastic Dual In-Line Package LOGIC SYMBOL VCC VSS RST PORT 0 XTAL1 XTAL2 EA PSEN ALE ADDRESS AND DATA BUS ALTERNATE FUNCTIONS Rx D Tx D INT0 INT1 T0 T1 WR RD PORT...
