2 / 10 page Philips Semiconductors Preliminary specification OM5234/OM5284 CMOS single-chip 8-bit microcontrollers 2 1996 Nov 01 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 Device OM5234 ROM code for application 5XX, etc. Frequency Range F = 3.5 to 16MHz I = 3.5 to 24MHz Package designator A = Plastic Leaded Chip Carrier B = Plastic Quad Flat Package P = Plastic Dual In-Line Package OM5284 X Y ZZ Device OM5284 ROM code for application 01, 02, 03 Frequency Range E = 3.5 to 16MHz I = 3.5 to 24MHz Package designator A = Plastic Leaded Chip Carier B = Plastic Quad Flat Package P = Plastic Dual In-Line Package / YYY Temperature Range B = 0 to 70 °C / PART NUMBER TEMPERATURE RANGE °C AND PACKAGE FREQUENCY (MHz) DRAWING NUMBER OM5234/FBB/YYY 0 to 70 °C, Plastic Quad Flat Package 16 SOT307-2 OM5234/FBP/YYY 0 to 70 °C, Plastic Dual In-Line Package 16 SOT129-1 OM5234/FBA/YYY 0 to 70 °C, Plastic Leaded Chip Carrier 16 SOT187-2 OM5284EBYY 0 to 70 °C, Plastic Quad Flat Package 16 SOT307-2 OM5284EAYY 0 to 70 °C, Plastic Leaded Chip Carrier 16 SOT187-2 OM5284EPYY 0 to 70 °C, Plastic Dual In-Line Package 16 SOT129-1 LOGIC SYMBOL ADDRESS AND DATA BUS ADDRESS BUS VSS VCC RST XTAL1 XTAL2 EA ALE PSEN RxD TxD INT0 INT1 T0 T1 WR RD SU00800 |
