LC66P408
4-bit Microcontroller with Built-in PROM
Overview
The LC66P408 is a 4-bit microcontroller with a built-in 8 Kbyte PROM. It is compatible with the LC6640X series mask ROM devices, making it ideal for prototyping and software development and testing. The LC66P408 features 33 user-defined options comprising output configuration, output level after reset, watchdog timer and oscillator configuration options. The output configuration options are open-drain, open-drain with pullup, and CMOS. The oscillator options are ceramic resonator, RC oscillator and external clock. The LC66P408 operates from a 5 V supply and is available in 42-pin DIPs and 48-pin QFPs.

PROM Programming The PROM can be programmed using a special adapter board, W66EP308D/408D for the 42-pin DIP and W66EP308Q/408Q for the 48-pin QIP as shown in the following figure, and a universal EPROM programmer.
The PROM address range is 0000H to 2007H, Addresses 2008H and above cannot be either programmed or read. The EPROM programmer should be Intel 27128 compatible with VPP = 21 V . The recommended programmers are shown in the following table. Please contact your nearest SANYO representative if you intend to use an alternative EPROM programmer.
Manufacturer ADVANTEST SANYO Model TR4943, R4944A, R4945 or equivalent EVA850 or EVA800 special-purpose programmers
The EPROM programmer adapter incorporates a data security switch. When this switch is ON, data is secure, and when OFF, the data lines are floating and the PROM can be programmed. Note that when the data lines are floating, the EPROM programmer will return an error. This error can be ignored.

APPLICATION NOTES Reset Timing The reset signal on RES should be held LOW for a minimum of three instruction cycles after the oscillator has
stabilized to ensure correct operation, as shown in the following figure.
After a reset occurs, all I/O ports are reset to open-drain output configuration with floating outputs, except for ports P0 and P1 which both have an output level after reset option. The output configuration of each port is then set using the specified options during the eight instruction cycles after RES goes HIGH. Program execution then begins from address 0000H. The LC66E408/P408 can also be reset while in hold mode (HOLD/P33 is LOW) as long as hold mode is exited before RES goes HIGH again. Reference Clock The external circuit for a ceramic resonator is shown in figure 6, and the recommended resonator and component values, in the following table. The oscillator stabilization characteristics are shown in figure 7. Figure 6. Ceramic resonator

The RC oscillator frequency is detemined by the external resistor and capacitor and has only been specified for Rext = 2.2 k and Cext = 100 pF. The frequency for other values of Rext and Cext can be determined from the graph in the following figure.
Figure 7. Ceramic resonator stabilization time The external circuit for an RC oscillator is shown in the following figure.
Preparation Procedure The preparation procedures shown in the following figure for DIP and QFP packages should always be followed prior to mounting the packages on the substrate.
Note that the QIP package should be heat-soaked for 24 hours at 125 C immediately prior to mounting.

Screening procedure The construction of the microcontroller with a blank builtin PROM makes it impossible for SANYO to completely factory-test it before shipping. To prove reliability of the programmed devices, the screening procedure shown in the following figure should always be followed.
Note that it is not possible to perform a write test on the blank PROM. 100% yield, therefore, cannot be guaranteed.
Ordering Information When ordering identical mask ROM and PROM devices simultaneously, provide an EPROM containing the target memory contents together with separate order forms for each of the mask ROM and PROM versions. When ordering a PROM device, provide an EPROM containing the target memory contents together with an order from. When ordering either an LC66404A 4 Kbyte or LC66406A 6 Kbyte mask ROM device, insert a jump command, or
