In addition to providing the substantial cost and performance benefits of the MC68EC000, the low-power mode of the MC68SEC000 provides significant advantages in power consumption and power management. The typical current consumption of the MC68SEC000 is only 0.5A in static standby mode and 15.0mA in normal 3.3V operation. The MC68SEC000 operates in either 3.3V or 5.0V systems. The remarkably low power consumption, small footprint packages, and static implementation are combined in the MC68SEC000 for low-power applications such as personal digital assistants, portable measuring equipment, electronic games, and batteryoperated hand-held consumer products. The HCMOS MC68SEC000 static architecture is a direct replacement for the MC68EC000, which offers the lowest cost entry point to 32-bit processing. The internal 32-bit architecture provides fast and efficient processing that satisfies the requirements of sophisticated applications based on high-level languages. In addition to being pin-for-pin compatible with the MC68EC000, the MC68SEC000 is object-code compatible with any member of the M68000 Family. Complete code compatibility lets system designers reduce time to market because they can rely on existing M68000 Family code and a broad base of established development tools. The MC68SEC000 will be available in two small footprint packages: the 64 lead plastic Quad Flat Pack and the 64 lead Thin Quad Flat Pack. The Thin Quad Flat Pack provides a very small package footprint (10.0mm x 10.0mm), making it an ideal choice for portable applications. The primary features of the MC68SEC000 embedded processor include the following: * Direct Replacement for the MC68EC000 -- -- -- Pin-for-pin compatibility with the MC68EC000 in the plastic QFP package Vast selection of existing third-party development tools for the MC68EC000 support the MC68SEC000 Software written for the MC68EC000 will run unchanged on the MC68SEC000 * Power Management -- -- -- -- Low power HCMOS technology Static design allows for stopping the processor clock 3.3V or 5V operation Typical 0.5A current consumption at 3.3V in sleep mode This document contains information on a product under development.

This processor provides a 24-bit address bus and a statically selectable 8- or 16-bit data bus, sixteen 32-bit registers, and seven interrupt levels. PREFETCH/ DECODE BUS CONTROLLER EXECUTION UNIT 24-BIT ADDRESS BUS 16-BIT DATA BUS CONTROL Figure 1. Block Diagram of MC68SEC000 HARDWARE/SOFTWARE COMPATIBILITY The MC68SEC000 embedded processor is hardware compatible with the MC68EC000, object-code compatible with the MC68EC000, and upward compatible with all members of the M68000 Family. Objectcode compatibility with the M68000 enables code written for the MC68SEC000 to be migrated without modification to any member of the M68000 Family. LOW-POWER MODE The MC68SEC000 provides static low-power operation. While in low-power mode, power consumption is reduced to its quiescent value while maintaining the internal state of the processor. The recommended method for placing the MC68SEC000 into low-power mode is described in Addendum to M68000 8-/16-/32Bit Microprocessor Users Manual, M68000 UMAD/AD. SIGNAL DESCRIPTION Figure 2 shows the functional signal groups for the MC68SEC000. These groups are briefly described in the following paragraphs. MOTOROLA MC68SEC000 PRODUCT INFORMATION 3 VCC GND CLK A23-A0 ADDRESS BUS D15-D0 AS DATA BUS PROCESSOR STATUS FC0 FC1 FC2 R/W UDS LDS DTACK MC68SEC000 BR BG BUS ARBITRATION CONTROL ASYNCHRONOUS BUS CONTROL BERR SYSTEM CONTROL RESET HALT MODE IPL0 IPL1 IPL2 AVEC INTERRUPT CONTROL Figure 2. Functional Signal Groups Address Bus (A23-A0) This 24-bit, unidirectional, three-state bus can address 16 Mbytes of data. It provides the address for bus operation during all cycles except interrupt cycles. During interrupt cycles, A3, A2, and A1 reflect the level of the interrupt being serviced, while A23-A4 and A0 are set to a logic high. Data Bus (D15-D0) This 16-bit, bidirectional, three-state bus is the general-purpose data path. Using the mode pin, you can statically select either 8- or 16-bit modes for data transfer. Asynchronous Bus Control Asynchronous data transfers are handled using the following control signals: address strobe (AS), read/ write (R/W), upper and lower data strobes (UDS, LDS), and data transfer acknowledge (DTACK). The address strobe signal indicates there is a valid address on the address bus. Read/write defines the data bus transfer as a read or write cycle. The data strobes control the flow of data on the data bus and the data transfer acknowledge indicates that the data transfer is complete. Bus Arbitration Control In multiple bus master systems, the bus arbitration circuit determines which device will be the bus master. The bus request (BR) indicates that an external device requires bus mastership. A bus grant (BG) indicates to all other potential bus master devices that the controller will release bus control at the end of the current bus cycle. 4 MC68SEC000 PRODUCT INFORMATION MOTOROLA Interrupt Control The MC68SEC000 provides seven levels of interrupts. The interrupt priority level (IPL2, IPL1, IPL0) inputs determine the priority level. Level 7 is nonmaskable and is the highest priority interrupt. Automatic vectoring, based on IPL inputs, is available with the autovector (AVEC) input. System Control The system control inputs include the RESET, HALT, BERR, and MODE signals. These signals can reset or halt the controller, indicate to the controller that a bus error has occurred, and select from 8- or 16-bit operating mode. Processor Status (FC2, FC1, FC0) These active-high, three-state function code outputs indicate the mode (user or supervisor) and the address space currently being accessed. The function code outputs are valid whenever AS is active. PACKAGE DIAGRAM The following package diagram applies to both the plastic QFP and TQFP packages of the MC68SEC000.
